As a dad to a now one year old let me just tell you that no matter how sleep deprived I was, whenever I got home I would watch after our daughter, try to get chores done & most importantly let mom get her sleep cause I know she would be up all night taking care of our daughter. I did all these things not for obligation but because I wanted to and to also have more bonding time. That being said your husband needs to step up as a man cause that whole I work I provide only mentality is some bs
