I have always used the Born Free anti colic bottles so far and they are really good but am finding the anti colic device a bit fiddly to wash. Neither of my babies had colic but the first one did have bad wind and this bottle was good at stopping that so we continued using them with my second baby. I tried a Tommee Tippee bottle today and the teat keeps being sucked into the bottle so my 6 month old can't get at the milk and he gets really frustrated. Can anyone recommend a good baby bottle?
