Questions about the flask
What is the Happymami flask made of?
The flask is high-grade stainless steel. It lasts, it resists corrosion, it is safe with food, and it does not change the taste of the drink.
Can it go in the dishwasher?
Wash the Happymami flask by hand, so the insulation and the steel stay as they should. A few parts may cope with a dishwasher, and hand washing still looks after it better.
Do not heat it in a microwave, do not freeze it, and do not use harsh detergents.
Is the flask BPA-free?
Yes. The Happymami flask is BPA-free, so the drink stays clear of those substances.
Is it leak-proof?
Yes. The seal and the lid with a secure closure keep it leak-proof. You can put it in a bag without worrying about spills.
Does it have a handle?
Yes. The flasks have a built-in handle, so they are easy to carry out, or just around the house.
When is a baby flask useful?
A baby flask is useful on walks, trips, clinic visits, or any time you need a prepared drink away from home. You can take water, milk or purée at the right temperature without a microwave or another heat source.
How long does it help keep food at temperature?
How long it holds depends on the starting temperature and the weather. The double wall keeps heat or cold longer than an ordinary container, so the feed is ready when your baby needs it.

Still have questions?
What is a good bottle for mixed feeding?
The best bottle is the one that fits your baby's needs and makes the move between breast and bottle gentler.
What happens if I give my baby both breast milk and formula?
Many families combine breast milk and formula successfully. What matters is following a rhythm that suits you and using a bottle shaped to your situation.
Which bottle is closest to the breast for mixed feeding?
At Happymami each bottle is shaped around the real details of your feeding and your baby.
How many bottles will I need for mixed feeding?
It depends on your routine. Many families start with one or two bottles and add feeds gradually.
What guidance should I follow for mixed feeding?
Keeping stimulation going, holding a regular rhythm and using a suitable bottle can help protect your feeding while you combine both.
