We decided to use glass bottles for our daughter because plastic just seemed to have too much potential for issues. I liked the Born Free option because they came with a silicone sleeve to help protect the bottles from breaking. My daughter is now 8 months old and they are the only bottles we have ever used. She typically nurses, however she has frequently used these bottles and they have been put through their fair share of abuse. Like any other kid she loves throwing her bottle down onto the floor and we have never had a bottle break or crack. Totally worth the money if you are looking into a glass bottle.
