We’ve had lansinoh since birth! She started taking bottles of breastmilk at night since 1 month old!
I love the Tommee Tippee bottles. And if you get the glass bottles you just have to replace the nipples which is pretty convenient
It took maybe a few days for my baby to transition but that was when he was about a month old. I swapped from de browns to Pigeon nipples (on Phillips avent bottles) and he caught on pretty quick!
