Sadly, I think Melissa is my second favorite (or maybe it would be more appropriate to say third least favorite?). Holly is my favorite, no doubt. She is classy and ladylike. She puts her daughter first, but is able to do so without putting down any of the other girls, cussing, or yelling. She also always seems to be looking out for the girls. She was the one who made she all of the girls got out of the room when everything between Kelly and Abby went down. I have no doubt that Nia will grow to be a beautiful young woman who is confident in herself.
Christi is my least favorite, mostly for the reasons I already brought up. Also, I have heard her speak badly about Maddie more than any of the other mothers. We can argue about whether or not we like Maddie, but she is still a 9 year old child. No mother should speak badly of another 9 year old. I also really dislike how she always says that Melissa slept with her married boss. I don't know if she has or if she hasn't, but it is clearly something that deeply angers Melissa, that she vehemently denies, and that has no business being brought up in the first place. I just think Christi carries herself in the least ladylike manner of the other moms. Can't deny that she loves her daughter, though, and is trying to raise her the best way she knows how.
That leaves Melissa and Jill. Personally, I wouldn't want my daughter raised by either, but I think I like Melissa more just because she doesn't complain about how Abby treats her daughter and then continue to bring her back each day. I don't know. Really, Holly is the only one I'm not face palming throughout the episode.
