Got Sleep?

Apparently I don't. My little 7 month old has decided he wants to wake up screaming and not go back to sleep for an hour no matter what I do. And of course my daughter now has a little cold is having a hard time sleeping. She was just up and getting out of bed from about midnight to 1 a.m. (at least that's when I fell asleep...hopefully she wasn't wandering the house). I hope this is just a phase because I have no idea what to do!
