there are three of them. the oldest is 30, the middle can be 23-25, and the youngest is 18-20 (but no younger than 18). colleen and her oldest child sort of grew together, she was a party girl and maybe not the best mom in the very beginning but she did level out. i'm also leaning toward saying the oldest has a different dad. then she got with her high school sweetheart, had the other two, so that's probably the only father figure her oldest has ever known.
all of the kids grew up in a supportive environment and were always encouraged to find their own path in life. on the surface, however, they didn't look like the conventional family. they were raised in the horror scene. colleen is like a modern day morticia addams with an affinity for saying 'fuck' a lot. so there is that. lol
