I plan on using tommee tippee bottles, steriliser etc with DC2. Hopefully I am able to express. I did have a TT breast pump with DS1 but didn't use it an awful lot as I had trouble with milk and feeding and the reviews I've read this time round for it aren't great so the question is, do I need to use a tommee tippee breast pump with the TT bottles or can it be a different brand?
