You are allowed to bring certain items for your baby in your cabin bag, which includes: soya milk for babies, sterilized water in a baby bottle, formula, breast milk or cow milk specially for babies and baby food in containers being 100ml or less. You would have to place it in a clear zip-lock bag being no bigger than 20cm x 20cm.  

If you do not have more than 1 litre in total the 100 ml rule does not apply to baby food, milk, or sterilized water. These do not need to fit in the transparent bag but you should have them ready for inspection by airport security.
