my 8 month old drinks milk well in sleep sometimes breast milk is not sufficient after consuming breast milk, looks like she want more. can I give formula milk immediately after breast milk? mix that extra or what to do

A. Yes you can give it immediately but not in much of quantity because we are not very certain about how much breastfeeding is your child having in one boy and what is the exact appetite in terms of milk in one feed so you can give formula but in moderation
