DH Vent

My husband and I both work from home and we agreed that he would watch the baby three days a week from 7-9am.   The baby then goes down for an hour nap and the nanny is there when he wakes up.

Our baby is really good in the morning and just starts to get fussy right before the first nap.

The problem is the DH consistently acts like he can't handle it.   I hear him sighing and muttering while he is caring for him and acting like there is some major issue.  I need to just work right through but instead I am helping/arguing with DH about the baby.

I am so frustrated because I don't feel like two hours is a lot to ask for.   In the early days,  we were both really struggling with how to take care of LO and sometimes we both felt we couldn't handle it.   But now we are almost four months in and I feel like he should have a grip on it by now.  I don't think it is that hard.  Ugh!!!!

It is so frustrating to me because it means I can't work, and I really want to explode at DH but then feel like a terrible mother because I don't want to get angry in front of the baby

Not sure what to do...
