I had b/a school kids all of last year, and I will never make that mistake again! I'm focusing on the 1-3yrs crowd, and I'm so much more relaxed. The little ones are alot more work physically, but overall they listen to direction and respect my rules. I spent so much time dealing with attitude/aggression/verbal bullying from the older ones(girls included)that I was left emotionally drained at the end of the day. The reduced pay with b/a also wasn't worth it. I have a great crowd of little ones now, and will never take school agers again.
