I'm trying to decide what to do about bottles for Little James. 

I've heard that Tommee Tippee bottles are awesome because they are the closest thing to mom. They have a wider base than other bottles. 

But I have lots of coupons for Avent bottles. 

All of my baby books mention nipple confusion at some point in the text. I don't know, is it a legitimate concern, or am I being overly sensitive?
