DD is just over 2 weeks.
At hospital as started her on SMA first milk, she drank that till about day 10 when I noticed her poos had started to go hard & she was really straining, only having one every other day. Suspecting constipation I switched her to cow & gate comfort. Her poops are now very runny & see more like newborn poop should be, but she seems to take forever to get this formula through the size 1 newborn teats, we noticed it's impossible to shake any out when doing a wrist test. The formula is so thick! We use both mam anti colic bottles & Tt back to nature, I bought some variflow teats for TT but she's so small she can't get them in her mouth, also tried TT number 2 teats but she took the milk so fast it came straight back up.
Do I try perhaps cow & gate first milk that's a bit thinner? Or do you think that would mess up her system again?
Or the mam bottles seem a little better, so not sure whether to persevere with just those. Still takes a long time to feed but not as long as with TT.
Also, how do you know if a baby likes the milk? She seems to pull a really disgusted face every time she takes the bottle, not sure if that's just what they do?! (FTM, PFB!!)
