Hey mama,
Perhaps let’s go into the size of baby’s stomach first.
So this is a guide.
Baby can’t hold too much in the stomach due to its size so frequent feeds is normal.
However, the consistency between breast milk and formula milk is different.
Do you supplement immediately after? How do you switch feeds?
I would advise you to put your post up in the BMSG group as well to ask for good advice from the counsellors there.
