What is this program?!?

I used to watch an american t.v program and I cannot remember what it was. It was about an american family, full of foster (or adopted) children. There was the Mum, Dad and Grandad and I don't remember how many children. I do remember one of the characters being called Cray, because when he was going to meet his real parents he worried that their surname would be Ola (then he would be called Cray Ola- haha). I also remember that the mother of the family got pregnant, and the children were worried that she wouldn't love them as much (but that was obviously resolved by the end of the episode). It was a comedy sitcom I'm sure. Some of the family were in the high end of their teens, and I think they hung out at some bar/cafe/club or something. There was an episode were they took pictures for a calender and the older boy didn't get to be the date he expected or something like that. There was also one were the Dad did a fire drill when they were all trying to sleep, I don't remember why. I don't remember a lot about it, but it's been wrecking my head for ages. If anyone knows what it was called, what channel it was on or who was in it, I would be over the moon. I just want reassurance that it actually existed haha. It was when I was child, like a 90's program back in the day of saved by the bell and the such like. THANKS!
