With DS I used Tommy tippee closer to nature bottles and steriliser but found the teat collapsed a lot. Ended up turning to Dr.browns bottles due to him having wind issues and they really helped but they were a real faff to wash and sterilise especially in my Tommy tippee steriliser!
This time round I considered purchasing the avent steriliser and their colic bottles (just incase baba has the same wind issues)
Just looking for people's opinions on these products or suggestions for other products.
