Week 35 of pregnancy: your baby's development
As you move into week 35 of pregnancy, your baby is going through a crucial phase of growth and development. At Happymami, drawing on our experience as midwives and on the most up-to-date scientific evidence, we want to give you a detailed picture of the progress your little one is making right now.
Physical growth: Your baby is gaining weight steadily, building up fat that will help them regulate their body temperature once they are outside the womb. This week, the average weight is around 2.4 kg (5.3 pounds), although this can vary. Their length from head to toe is approximately 46 cm (18 inches).
Organ development: Your baby's kidneys are now fully developed, and their liver can process some waste products. Most of their basic physical development is complete, and their main job now is to keep growing and maturing.
Nervous system maturation: Your baby's brain continues to develop rapidly and is starting to regulate some bodily functions such as breathing and temperature control.
Getting ready to breathe: Although your baby has been getting oxygen through the placenta, their lungs are almost completely developed and ready for outside air. They are practising breathing by inhaling and exhaling amniotic fluid.
Movements and reflexes: Movements may be less vigorous than before, as the space in the womb becomes tighter. However, you should still feel regular movements, which are a sign of your baby's wellbeing. Reflexes such as sucking are becoming more refined, preparing your baby to feed after birth.
Sleep: Your baby already has a sleep pattern, alternating between sleep and wakefulness. They may react to sounds, light and touch, which shows greater sensitivity and sensory development.
Physical appearance: Your baby's skin is becoming smoother and lighter. The lanugo, the fine hair that covered their body, is starting to disappear, although some may still be there at birth.

Week 35 of pregnancy: symptoms
When you reach week 35 of pregnancy, your body is in the home stretch of this incredible transformation, and you may experience a range of symptoms. At Happymami, we want you to be informed about what you might feel during this stage, always backed by our experience as midwives and by the scientific evidence.
Fatigue: At this stage, it is common to feel more tired. Weight gain and hormonal changes can make daily activities more exhausting. Listen to your body and rest as much as you need.
Pelvic pressure: As your baby grows and gets into position for birth, you may feel extra pressure in your pelvis and lower back. This can also mean needing the toilet more often.
Difficulty sleeping: Finding a comfortable position to sleep in can be a challenge, and you may wake up frequently during the night, whether because you need the toilet or because of your baby's activity.
Braxton Hicks contractions: These practice contractions may become more frequent and more intense as you get closer to birth. Although they can be uncomfortable, they are normal and help your body prepare for labour.
Swelling: You may notice swelling in your feet, ankles and hands due to fluid retention. Although this is a common symptom, if the swelling is sudden or severe you should see your doctor, as it could be a sign of pre-eclampsia.
Heartburn and slow digestion: Your baby's growth can put pressure on your stomach and intestines, which can lead to heartburn or indigestion. Eating small, frequent meals can help relieve these symptoms.
Changes in vaginal discharge: You may notice an increase in vaginal discharge. If the discharge changes colour, has a strong smell, or if you experience itching or burning, you should consult your doctor.
Intense emotions: As the day of birth approaches, it is normal to experience a rollercoaster of emotions, from anticipation and joy to anxiety and fear. Talking about these feelings with your partner, friends, family or a professional can be very helpful.
Remember that if you have any concerns, or if you experience symptoms that seem unusual to you, do not hesitate to contact your healthcare team.
Week 35 of pregnancy: whooping cough
As you move towards week 35 of pregnancy, it is essential to consider important health matters that can affect both your wellbeing and your baby's. At Happymami, we highlight the importance of preventing whooping cough, an illness that can be particularly dangerous for newborns.
Clinical guidelines recommend vaccination, as it is a powerful tool in preventing whooping cough. The Tdap vaccine is recommended during the third trimester of every pregnancy because it provides two key benefits: it protects the mother from infection and, more importantly, it transfers antibodies to the baby, offering a layer of protection until your little one can receive their own vaccines.
Receiving the Tdap vaccine between weeks 27 and 36 ensures the maximum transfer of maternal antibodies. This is crucial, as babies are not fully vaccinated against whooping cough until they are several months old.
Knowing the symptoms of whooping cough is vital. If you experience a persistent cough that gets worse over time, it is essential to seek medical attention immediately. Early treatment can not only help you recover more quickly, but also reduces the risk of passing the illness on to your baby.
Week 35 is a time to focus on caring for ourselves, keeping health as a priority while you get ready for your little one's arrival.

How does the mum-to-be feel at week 35?
Reaching week 35 of pregnancy is a significant achievement on your journey to motherhood. At Happymami, we understand that this period can be as exciting as it is exhausting, and we want to make sure you feel supported and understood.
Physically, you may feel heavier and find that you may feel tired more often. Your baby's growth is not only visible but also tangible, with movements that can be both wonderful and uncomfortable. Pressure on the pelvis may intensify as your baby gets into position for birth, and this can mean more frequent trips to the toilet and a slower, more careful walk.
Braxton Hicks contractions may become more noticeable, preparing your uterus for labour. Although they are normal, if they become regular and painful, it is important to contact your healthcare professional.
Emotionally, you may be on an emotional rollercoaster. The anticipation of meeting your baby can be mixed with anxiety about birth and the changes ahead. It is normal for doubts and fears to come up, as well as a feeling of impatience to finally see your child.
On top of that, mentally you may be going over lists of things still to do, from preparing the baby's room to making sure everything is ready for the moment of birth. The need to have everything under control can be overwhelming, so it is essential to find moments of relaxation and time to switch off.
Week 35 of pregnancy: Happymami tips
At week 35 of pregnancy, you are at a time of great expectation and preparation. From Happymami, we want to give you advice based on the latest scientific evidence.
Rest becomes a fundamental pillar. Listen to your body and allow yourself moments of rest whenever you need them. Restful sleep is essential for your health and your little one's. If your doctor approves, continue with gentle exercise such as walking or swimming, which will not only help you stay active but can also relieve stress and promote good blood circulation.
Nutrition remains a key aspect. A balanced diet, rich in iron, calcium and protein, will support your baby's continued development and keep you strong and healthy. Do not forget hydration; drinking enough water is crucial for maintaining a good flow of fluids in your body and for your baby's wellbeing.
Now is also the time to think about the final preparations for birth. If you have not packed your hospital bag yet, do it calmly, making sure you include what you need for yourself and your baby. Review your birth plan, if you have one, and share your wishes with your healthcare team. Consider attending a birth preparation class if possible; this can give you valuable tools and boost your confidence ahead of your child's birth.
Antenatal care should not be neglected. Keep attending your medical appointments regularly, as they are essential for monitoring the progress of your pregnancy and your baby's health. Also, if you have not done so yet, talk to your doctor about the Tdap vaccine to protect yourself against whooping cough and give your baby immunity.
Emotional support is just as important as physical care. Share your emotions and concerns with your partner, friends or a support group. You are not alone on this journey, and expressing what you feel can be incredibly liberating and comforting. Practices such as meditation and prenatal yoga can be helpful for managing stress and keeping you centred and connected with your baby.
Finally, make the most of this time to learn about birth and newborn care. Reading and preparing can help you feel more in control and ready for the challenges and joys ahead. Also make sure your home is ready for your baby's arrival, from the safe installation of the car seat to having the space where they will sleep ready.
Remember that A Happymami bottle designed to match the shape of your breast can be a great help, whether you plan to breastfeed, combination-feed or use formula from the start.
A Happymami bottle shaped like your breast increases the likelihood that your baby will accept it and protects against teat-nipple confusion in newborns.
Frequently asked questions about week 35 of pregnancy
Is a breech birth always a caesarean?
A breech birth, where the baby is positioned to be born bottom or feet first instead of head first, does not always result in a caesarean, but it does increase the likelihood that one will be recommended.
In some cases, an external manoeuvre known as external cephalic version (ECV) can be attempted to turn the baby into a head-down position before birth. Discuss it with your midwife or gynaecologist, as it can be a good option.
Is it normal to feel fewer baby movements at week 35?
As the space in the womb gets smaller, some babies may move less. However, you should still feel regular movements. If you notice a significant decrease in activity, contact your doctor.
What should I do if I have contractions at week 35?
Braxton Hicks contractions are common and often intensify towards the end of pregnancy. If contractions become regular, painful or are accompanied by any other sign of premature labour, such as changes in vaginal discharge or pelvic pressure, it is important to seek medical care.
How can I tell if the pain I feel is premature labour?
The pain of premature labour can include regular contractions before week 37, lower back pain that feels different from previous aches, pressure in the pelvis and changes in vaginal discharge. With these symptoms, it is crucial to consult your doctor immediately.
What tests or examinations should I expect at medical appointments from now on?
During medical appointments at week 35, you may be offered foetal monitoring to check your baby's wellbeing, an ultrasound scan to assess position and growth, and tests to detect Group B Streptococcus (GBS) and other conditions.
Should I be sleeping in a specific position?
Sleeping on your side is recommended, preferably on your left side, to improve the flow of blood and nutrients to your baby. Avoid sleeping on your back, as this can cause problems with your circulation and your baby's.
Is it safe to fly during week 35?
Many airlines have restrictions on travelling at the end of pregnancy. In addition, flying can increase the risk of deep vein thrombosis (DVT). Consult your doctor before making any travel plans.
Which signs mean I should go to hospital or call my doctor?
You should seek medical care if you experience any sign of premature labour, vaginal bleeding, a significant decrease in your baby's movements, or if you have symptoms of pre-eclampsia such as severe swelling, a severe headache, changes in vision or pain in the upper abdomen.
