i use the Dr Browns on Rhiannon, i had to switch from Avent when she was 9 weeks because she wasnt winding so well on them, but with Dr Browns they have this internal vent that stops a lot of air going into baby's tum and now we dont even have to rub Rhiannons back she burps as we sit her up, they are pricey and a bummer to clean with the brush before steralising as each bottle has 6 parts (lid, teat, screw neck, top of internal vent, bottom of internal vent and the bottle itself) but compared to how she was its worth it,
if you need any other info msg me and ill help if i can x
p.s just checked your toysRus link and the US Dr Browns look totally different to the Uk ones, heres a link to the ones ive got..
