My daughter is 5mo old as well :)
I hope someone has some advice for you. My husband just went to that schedule actually. He's in the Navy and they just moved him over to security (he'll be there 6mo). I'm also dealing with my husband not helping out much b/c he wasn't here for the birth or the first 8wks of her life, so he really has no clue AND he leaves all the time. That makes it so super-duper hard for her to even get used to him.
A major piece of advice is to find someone around that you may be able to trust to watch your son for 30min or so. I actually used to have a friend come over sometimes just to watch Evelyn while I napped, so I was still home but someone else was there to care for her. My friends have more patience with Evelyn than my husband, which is tiring and annoying.
I didn't have a great night last night so I think I needed to get that off my chest heh.
Anyway, just wanted to let you know you aren't alone. I say definitely keep that husband picking up after himself. Even if he does it right before leaving for work. I know when my husband came home this morning he was very exhausted. I'll just have him pick up his crap when he wakes up before leaving for work again. anyway, *HUGS*
