These bottles are convenient because the baby can also be positioning his little hands in "bowls" ... more teats have the same shape as the nipples of a woman and for babies who are breast-ca allows them to pass more easily from a bottle ... For my part, my daughter more easily accept this bottle than any other that I have been able to take him ... even if she plays more with it drinks the hussy! ;) She is 6 months old so I know it's going to take him a little time ... I do not care for me .... and then the bottle was recommended to me by a midwife who gives it to cousin daughter 2 1/2 months (breastfeeding too! :)). I therefore advise you! here and then beat the price!
