kids in bed

I am not a fan of my children sleeping in my bed. I don't sleep well. Then I turn into a cranky mom the next day. So when Alex joined Jeff and I in bed. I wasn't really happy, but he was on Jeff's side of the bed so I just rolled over to go back to sleep. It didn't take me long to realize the sound of him snuffing his nose was not from a cold, but a bloody nose!!! So needless to say Jeff and I didn't get right back to sleep. Plus both beds needed their bedding washed.
Two nights later in comes Seth with a croupy cough saying he can't breath. All is well and for both boys, but I am just repeating-- I don't sleep well when the kids come into my bed at night.
