Pre partum rage

My youngest is almost a year old, but he’s the loudest baby out of all my kids, he loves to scream all day and pull my hair I usually keep it wrapped or in a bun when I can. But lately his screaming has irritated me so bad, I am sleep deprived as I have switched to third shift & I come home to 2 kids that need my attention, on top of being 4 months pregnant.

His dad just comes in plays with him a little & will leave out when ever he wants not even asking if I need a break or if I want him to do anything before leaving out. He just recently started hanging with our neighbors who have no job so they have nothing but time to hang out in their garage & drink all day. I’ve expressed to him that there has been a shift in our dynamic & it’s effecting drastically. & I hate to even say my baby is even irritating me but he is, tonight I placed him in his bed & had to step away gather myself & come back. At this moment I know this issue is way bigger than just being irritable, I just don’t know how to make my spouse understand with out sounding like a lunatic.
