I am in a similar boat. My dh will help with our 4 3/4 month old ds occasionally but, now that we've been putting ds to bed earlier every night, by the time dh finally gets home, he usually only has ds for about 30 minutes before it's time for ds to go to sleep. Dh will take the baby on the weekends so that I can sleep in, however, it's kind of hard to sleep in when dh is coming in every 15 minutes of so asking me this and that. "I don't know why ds is crying. Could he be hungry?" "How much do you usually feed him?" As always, it's things that could either wait or that dh should know by now but he just HAS to bother me, I think because he's resentful that I am sleeping in while he has the baby.
Other than the little help I get from dh with the baby and housework (dh does the dishes occasionally but nothing else), I have no one to help me. My mother's and mil's idea of "help" is to come over and take the baby from me. I don't need help caring for my child, thank you very much. I can manage that on my own. What I need help with is everything else - the housework, errands that need to be run, yard work, etc. But if I dare to complain to anyone, all I ever hear is "Welcome to motherhood." Either that or "Well..*I* did it all by MYself so why can't you?" I swear to you, if I hear either of those phrases ONE more time, I'll snap.
I also don't have any friends other than online ones so that makes it hard too, along with not having a second car. Basically I'm stuck inside the house all day with no one to talk to other than ds.
Maybe you can do what I'm trying to do and look into joining some mommy and me groups? That might help. You could also try talking to your dh about helping you out more but, if he's anything like my dh, it won't do much good.
I wish you lots of luck. Sorry I couldn't help more.
