You will fight with your hubby and you will nag him... I don't know if it's the tiredness, the slight bitterness that your life has changed so much and his hasn't been as affected, the frustration that occurs when you do things differently, or, more than likely, a combination of everything!
It was a priority for Dan and I not to fight and not to nag or criticize each other for doing things differently... but, fact is, once baby comes, everything changes. The first six weeks are hard. You're both tired, you're scared, you're nervous, you're worried, you're adjusting, and you're just trying to do your best.
I think the key for us has been talking about it - explaining why we're nagging, why we're angry, etc. We usually do this after a "break time" so we each have time to cool down and realize where we were wrong cause our fights are usually the result of both of us doing something stupid... one person starting stupid and the other reacting stupidly! ha ha ha.
