Chapter 17. Baby’s Excretion
When you combine breastfeeding and formula feeding, his stool tends to be watery. If his appetite drops or he begins vomiting, seek medical attention as soon as possible.
As long as your baby is feeding well, active, and healthy, there is no need to worry. Passing gas frequently indicates good intestinal motility, which is normal. In the first few months, breastfed babies often have loose, watery stools that may contain small particles or have a slightly sour smell and can be expelled along with gas – this is also normal.
Compared to breast milk, formula can be harder for babies to digest. Therefore, if possible, try to breastfeed as much as you can.
