I used Avent bottles with my 1st two. I've had to chuck them all as I deceided that no. 3 could do with some fresh ones. Are there any on the market, I'm wondering, that are better. I was happy with Avent but if someone can persuade me that there's something better out there....? Ds and DD both were breastfed but I intro'd a bottle at 8 wks. or so. Both were a bit colicky too. Any recommendations?
