I think that's fine, every baby is different so if it suits your little one and they are feeding well then I'd leave them where they are xx
It’s fine. If they’re happy with it, no need to change. We swapped my little girl over to size 2 and it was too fast for her and she kept bringing most of her milk back up. X
Thank you guys I’ll keep him on size 1 for now 😊
It should be fine long as the baby is feeding, my LO is the same age, we swapped him to size 3 and it was too fast and he was getting fussy. He’s back on size 2 and seems content
