I have quite a lot of TT bottles that I'm happy to reuse from baby 1 for baby 2 (I appreciate baby 2 isn't guaranteed to agree). I'm a bit disappointed that they seem to be £4.50-5 for a pair of teats but I can get a set of 6 bottles and teats for £10 from amazon. Am I missing something? It seems pretty wasteful to have to get new bottles, but loads cheaper.
