It sounds like you have your hands full. I'm also a single mom and my youngest started school this year...
I'm not dealing with the behavior problems that you are, but I have her firmly attached to me leg and in tears every morning. I just found out today that she is the lowest of the low on the scale for learning. (she is ODD) and has a hard time concentrating for more then a few minutes.
She was born the end of June and if she is unable to adjust in the next two weeks, I will (as hard as it is) pull her out and let her try again next year.
I think it is a decision we must make, we know are children better then anyone else.
Hang in there!
