It takes 2 to make a baby, Kimmie and he has to realise that.
My Dh works full time and when the children were born he took his turn, bathing, nappies, taking baby out for fresh air, all that. He has to face his responsibilities. If he is unwilling to manage with her at this young age how will he get on when shes walking? talking? at school?
I am sorry you are having it tough.
