Hi all. I've been using AVENT bottles for my DS for weeks now (he's 10 weeks old). Have been getting on with them fine, but having seen some of the threads here, I'm beginning to wonder if I should be using Dr Brown's or BFree bottles. DS has been having a little cry (very brief) after some feeds recently and I'm wondering if wind is the problem. This is a very new thing - previously he would never cry after a feed. He brings up wind normally after every feed with not too much fuss. I had always thought that Avent bottles were supposed to be very good for preventing colic, but now I'm beginning to wonder. Also, the other thing is is that we have the avent microwave steriliser along with all the bottles, teats etc - could be expensive to replace the whole lot, but would do it if people thought it was worth it - after all, nothing is too much trouble when it comes to giving him the best as I can't breastfeed him.
