maybe he doesnt know how to help? if he never have helped you around the house (since that is the only way he can help you at this time) he most definitely doesnt know you need help- on the other hand he may be jealous. but that's kind of too soon for that. let's give him a benefit of the doubt he simply has no idea you need him help you
none of you say how old you or your partners are - i'm too lazy to go and look at your profiles (on dial up and opening all pages is a nuisance), but i am guessing you are young parents? early to mid 20s? i'd be sad for you if you're in your 30s or older and this is happening, there would be no excuse then. sadly a lot of guys are being raised STILL believing mother's job is to take care of everything and often without help. did you discuss his role before the baby came? it sounds like both of you are young and this is your first child. so much stuff to learn and no one is to blame here but i'm sorry you feel like you're going it alone. olokiju has a nice point if you have the time together to enrol in parenting classes or even support groups for parents. <br />
perhaps your man is afraid of what he can/cannot do and doesn't want to step on your toes in any way. talk as much as you can about helping each other out and suggest some alternate nights with being up with baby in the wee hours just so you can get a bit of extra sleep. even if you are breastfeeding, father can help out by burping, changing baby and cleaning him up when he needs it while you get back to sleep. babies exhaust parents for months, that is a fact. get his help especially with that and be loving with one another about it, being supportive to each other helps both mum & dad feel good. good luck.
My daughter is three months and I am going through the same thing. I am sorry :(
Let the baby's father know exactly what you need from him in the way of help. Let him know how hard it is for you to have to do everything by yourself.
