I was sceptic about all
I was sceptic about all the reviews but to mu surprise my little one took it first time he hasn't done this woth any of the other 4 brands i have tried. He is still a lottle fussy but after a few minutes, a little jig and persistence he takes it even for me. He is 3months and best uses the xs teat. So we are using it once a day to get him used to it.
