Re: Anyone use glass bottles???
We used lifefactory at first and really liked the silicone sleeve. We never broke one of those. Then we switched to munchkin when we needed the bigger size (got them on free cycle) and haven't looked back. DS broke one by throwing it onto the tile bathroom floor. I did make felted wool covers for the munchkins but I don't know if that would work as well as the silicone. I'm pretty controlling about how and when and where we use the bottles for fear of them breaking, but the times that we have dropped them they have been very sturdy!
