i agree with everyone...get a babysitter! it will be a much appreciated and well worth it expense. who knows..if you hire a sitter just so you can sleep and relax, maybe you can get a cheaper than usual rate since you will be in the house still. i just interviewed sitters and most of them were college students adn all of them were fine with $10-11 hr. (which i think is considered a cheap rate, right?) and definitely hire a sitter or maybe a family member can come on the weekend and do a DATE NIGHT!!! it will make such a difference.
good luck and try to get more sleep...
