bottles?

[Fizzy]

hiya, my daughter is now 7 months old and i want to try some bedtime milk for her such as the cow&gate bedtime milk, but i have heard from a lot of mums that the formula is really thick? just wondering what bottles i should get for her then and what teat sizes? im currently using the tommy tipee ones number 3 size teats but a few mums have said even that is difficult to take the thick formula in?

please suggest a few bottles for me to try for her for thicker formula's! thnx
