I just read your post below and it's so similar to what I deal with on a day to day basis that I could have written it - the yelling, the fighting, and sadly the not wanting to spend time with the kids. I can't even put into words how much I love my kids but as a stay at home mom who also runs a business from home sometimes I want to jump out a window. I'm not saying that I would ever do it but it's alot to handle. My DH comes home and the kids run to him as if he just brought home ponies and ice cream while I stand off in the background and observe all this. Being a mom is the hardest job and if anyone ever tells you differently they've never done it for even a day. If you ever need someone to call on please don't hesitate to page me on here.
As far as the potty training my DD is going to be 4 in June and just got out of diapers 2 months ago. She was a nighmare to train. Oh and I yelled at her yesterday for peeing on the floor outside the bathroom. After all the comotion I scooped her up and held her for a while. She knows I still love her.
hang in there. We all have our moments.
