I am currently 31 weeks and have massive 15 year age gap between big son and soon to be little son. I kept my 15 year old Tommee Tippee bottles as always planned on having more (not this big of a gap though). I don't want to buy new bottles, so was wondering whether anyone knows if the new teats fit in the old bottles. I don't want to buy loads of different types if someone can tell me yay or nay on here 🙃
