Many mums worry about whether the amount of breastmilk they are producing is enough to feed their baby. Ardo Belly Balls have been designed as a supportive teaching product to show how small the stomach of an infant is, and also to show that the amount of breastmilk they receive is, as a rule, completely sufficient.
Each size of Ardo Belly Balls corresponds to the estimated average size of a new-born’s elastic stomach. The average size of a new-born baby’s stomach will be:
on the first day: 5-7 ml
on the third day: 22-27 ml
on the fifth day: approx. 57 ml
