How to make
Wash an apple, peel it and clean it from its seeds. Boil the apple and put it into a bowl that is convenient enough to mash it in.
Peel a banana and mash it with a fork. Add it to the boiled apple in the same bowl.
Mash the fruit. Then add the formula (prepared according to the instructions on the box).
If the baby is breastfed, you can add breast milk instead of formula.
