are parenting classes helpful? and at 6 months is it too late to join?

I could only afford to take a breastfeeding class. I liked it and found it very informative. I was already like 7 and half months along. I wish I could have taken more classes. I am a bit of a nerd like that. I think 6 months is a great time to take a class.

I start breastfeeding classes this week
