Lansinoh v mam bottles

[Mummy2925]

My lo is formula fed and we are using lansinoh bottles for his milk Which he took to well and was happily finishing his bottles.
now he’s only 3 weeks old (and quite a “lazy” baby since birth) but he is taking ages to finished his bottle of only taking a oz and goes to sleep.
now my understanding is that the lansioh test makes them “work harder” for the milk so the don’t get a bottle preference when breast feeding, could it be that he’s getting tired in the bottle , would a different brand suit better?

last night he was up every hour only taking a oz at a time 😫

What teat size are you using? I used mam for expressed milk now & again from 4 weeks and stuck to 0 size but my friends who formula fed went up teats quite quickly I think, I’m sure someone who knows more will comment soon but just thought was worth mentioning

@Tree6543
I’m using the lansinoh size s teat it’s 1 month + the next size is 3 months + which seems like a big jump so soon ? :(

I’d definitely try a bigger teat
