Hello, I used Avent classic with my daughter initially.
I liked them, they were fine. I did swap after a few months because she appeared to have really bad colic.
At the height of sleep deprivation I swapped -at great expense -to Dr Browns. I don't really know if they helped or whether it was just that it felt better because I did something about it, but at the time I was convinced it reduced colic.
However, I actually hated using the Dr Browns because they leaked everywhere and had hundreds of bits.
I reverted to Avent a few months after when she had settled down as they were easier to use and wash. The teats were very similar so baby didn't bother much about the difference and I think they were similar price wise.
I've bought MAM ones for baby this time round as they are self sterilising and mainly because they were on offer and pretty. I'm not altogether convinced that there's a huge amount of difference between any of them though, think it may be a trick to get sleep deprived new parents to spend more money. It worked with me!
I think that does differ if you introduce the bottles much later as babies seem to get more picky about what the drink out of if they've been exclusively breast fed at first. Had a few friends who struggle to get their babies to take certain brands when they stopped breastfeeding.
Hope this helps!
