New baby causing strain on marriage...advice?

Hi ladies, my husband and I have been married a little more than three years and have been together for five. We just had our first baby 18 days ago and she is beautiful and perfect and we couldn’t love her more!

The hardest thing since bringing her home has been that we both feel like we aren’t communicating well AT ALL. Between the worries of just being new parents and caring for a newborn and being sleep deprived, we are both irritable and it seems anything we say to each other gets taken the wrong way!

We have always had a great, healthy relationship and have never had any serious issues. We are BEST FRIENDS and we hate to argue or fight.

Here’s the situation: he has been working 50-60 hour weeks (5am-3pm 5-6 days a week) and I have been on maternity leave at home with the baby. I am breastfeeding so I am with her all day while he’s at work and I’m up with her all night however often she wants to nurse. I just feel like he always has something to say about what I am or am not doing for the baby and it gets under my skin because he hardly gives me a break when he’s home and he feels like he deserves to rest and sleep when he gets home from a 10 hour day. I don’t disagree but at the same time, do I not deserve some time to myself (I mean, like 45 minutes to shower and get some housework done)?? I feel like I have to ask him for everything I need and it just seems like he is annoyed anytime I ask him to help me with something. Honestly I just want him to offer to take the baby so I can have a few minutes to myself. And he feels like I am snapping at him and being defensive all the time and I shouldn’t be taking it out on him. It seems like we both are feeling some resentment toward each other and I absolutely hate it!!

Any advice, mommas??
