Yeah, you guys are probably right that she's stressed. But I don't know why.
I could believe she is getting tired of Taggart constantly bugging her, but she still plays with him. Maybe I need to spend one on one time with her more often. I think she really enjoyed it a couple weeks ago when my brother and SIL took Taggart home with them and it was just her and I again....like old times.

Thanks for the ideas everyone. I will keep you updated and let you know if anything new occurs.
