Loving dads and their lack of help

A bit of a rant, sorry. So we all know as moms we put baby first. No matter what comes, we do what we must for our baby. Sleepless (sleep less) nights, stinky diapers, spit up that goes into your every crease. It doesn't matter, we just deal and do, because baby depends on you. Why is it that dads get off the workload? Goes to the other room at night because baby keeps him up (we use a co sleep camping cot) and gets a solid 8hours. Hasn't done a pee diaper in 7 weeks, nevermind a poo one. Plays xbox and gets frustrated when I dare ask for help or to keep an eye on the SLEEPING baby in his cot (we have one next to our coffee table, so dad doesn't need to go to a room or check a monitor) so I can do a round of laundry or fix a bottle in the kitchen 10 steps away. Is it me??? I'm so annoyed with my husband "slacking". Asking him to help out more and share more tasks just gets met with the same excuse, "you're doing such a great job, I don't need to help with that". I do thank him for helping with burping and the occasional tummytime they do together but I really expected a bit more of shared responsibility like we talked about in the pregnancy. 4am feeding and feeling a bit alone, rant over.
