Okay, here are my opinions.... just warning you, I am very opinionated :-)
Maci- ABSOLUTELY by far the best mom! She is so loving, always puts Bentley first (especially with Kyle coming into her life) and acts way more mature than her age! :) I love love love Bentley... he is SOOOOOOOO cute! Kyle is so sweet and Maci & him are so cute together! He'd be an awesome role model in Bentley's life.
Farrah- She does crazy things. Like sell her car over the internet and get scammed *stupid*. Leaves a crying baby on the floor in a dark room. *stupid*. etc.... I feel bad for her though, she seems like she is trying considering her circumstances. I hope things turn out better for her soon.
Catelynn- To be completely honest, I am SO sick of Catelynn & Tyler this, Catelynn & Tyler that. When they come on the show, I don't even pay attention because its always another fight about the phone records, moving around, complaining... etc etc. When they talk about Carly, though, I do pay attention as they were very mature and brave to chose adoption and I praise them for that :)
Amber- I don't even know what to say. First of all, they REALLY need to clean their house up. It's disgusting!! One second they are happy, the next fighting. It's not healthy for them or for Leah. And Amber has done a really good job losing weight, and I think Gary needs to lose some as well. Gary needs to grow up, BIG TIME! Take care of yourself & your family! Get a job!! And be a man.
Soooo... do you still want to have a discussion with me? Haha, I told you I'm very opinionated :-)
