Teething baby and horny hubby

Jessica
I have 2 kids at home, a 3 year old and a 9 month old. It's been 2 weeks of teething and not sleeping. I don't get more then 3 hours of sleep a night then I have to take care of the kids all day. I'm so exhausted. As soon as I get the baby to sleep my hubby is all over me. He does not understand at all just how exhausted I am.
