Eh, these kinds of things always turn into debates. I get a mom putting her kid into a class early. Honestly sometimes it's necessary. While quite a few do it due to social pressure I think some honestly feel it's a good thing for their child.
Before I had kids, I thought if you didn't breastfeed, babywear or stay home with your kids you were a terrible parent. Now I realize there are so many ways to be a great parent that did not fit into my previous beliefs. We all do things differently and that is fine. In fact, it's great!
