Mother-in-Laws

Let me preface this by saying that normally I like my mother-in-law. She's been very good to us the last few years by watching our kids a lot and stuff like that. Lately, she's been annoying the crap out of us because she has a noticeable preference to our son over our daughter. We've been subtly having her watch our daughter more and more without our son. In fact, last Sunday after church, when she normally always asks to take Jadyn home for the afternoon (never Trinity unless we ask her to take Trinity also), we managed to get her to take just Trinity while we took Jadyn to see The Incredibles (good movie). However, today takes the cake. I am, at the moment, thoroughly pissed off at my mother-in-law. The kids spent New Years with Grandma. Couch and I rented a jacuzzi suite at a local hotel and had a party of our own (with about a dozen families who were all there together, was quite a party actually). Today we went to pick the kids up. As always, Trinity ran for me when she saw me. I picked her up, took one look at her and got PISSED. I preceded to bite my tongue, tell Couch to get their bags, and got out of there as quickly as possible. The reason...My daughter now has bangs. Yes, my mother-in-law CUT my daughter's hair. I probably wouldn't have cared except for two reasons. One, we were growing her bangs out. I hate bangs. And two, more importantly, I was waiting until she was two to go and do the whole big First Hair Cut thing. Yup, that's right. My mother-in-law not only gave her a haircut but it was her FIRST haircut. Trinity is Couch's and my's last child. We can not have anymore. I am a very sentimental type person and that fact that she stole this milestone from me has me extremely upset. As soon as we got in the van, Couch asked me what was wrong. He hadn't noticed. He suggested that maybe a toy or gum had got caught in it and she'd had no choice. I pondered that, but figured she'd have mentioned it if that was the case. I had him call her when we got home. Nope, no toy, no gum. She said "yeah, I put it up in pigtails and there was some sticking out so I cut it off". WTF? She and I have had conversations about the fact that I was waiting until Trinity was two to cut her hair. We've talked about her bangs and how I wanted to grow them out. I just don't understand. She asked if I was upset and proceeded to say she was sorry a bunch of times, but still. Like Couch told her, I will live (and yes, I know there are more important issues in the world to get upset about) but I'm still mad.
