Off to Work Tomorrow

I'm really nervous about my first day back at work. It's not that I'm nervous about work...even though I haven't been there in practically 4 months...but I'm nervous about leaving Brennan. Colin doesn't worry me anymore, he's a big boy now...but Brennan is so small. I know that I don't really have anything to worry about, but I'm sure I'll call the sitter about 1000 times tomorrow just to check on them.
