My baby had been on mostly bm 4 out of 6 feeds until 6mo. Recently switched her to total fm. Was on nan ha 1 and now on nan ha 2 but noticed she had a really hard time finishing up her milk and her intake used to be 150ml bm but now finishing even 90ml fm is so hard for her. What could be the reason? Should i switch brand? Which brand is not so thick? I also noticed my bb pants alot when drinking fm. Thanks in advance!
