My one month old baby keeps vomiting my breastmilk
Question: My one month old just recently started vomiting up my breastmilk but not formula - what could be the reason? I thought breastmilk was better then formula.
Heidi's Answer: Hi there, Throwing up a bit of milk is normal at this age. Most babies, whether formula or breast fed, do it.
Vomiting more with breastfeeding may have to do with feeding position, maybe he is more upright when formula fed? Or your milk may spray out (good supply!) which makes him take in more air. If this is the case, press out the first gusts of milk before offering it to your baby. And always make sure he empties the first breast completely before offering the second side.
It's worth trying these out because as you say breast milk is better, for so many reasons.
If the vomiting is very frequent and in large quantities, and it comes out with force, that may point to a form of reflux.
