Nope your are not wrong at all in fact… I you weren’t a stay at home mom you would have to pay someone to be that same stay at home mom. You are not his mother and that baby wasn’t made by the Holy Spirit. He needs to do way more than that. And you shouldn’t feel guilty for demanding it. I even think you will realize later on that you are better of alone than with a man like that.
You are not wrong and you’re right to feel frustrated. Even if you’re at “home” you are working. Being a mom is nonstop. That work and your time is valuable. You deserve rest. His time is not more valuable than yours. I highly recommend you check out two books on this topic: How to Keep House while Drowning (Davis) and Fair Play (Rodsky)
It's ridiculous he isn't helping pay for babies stuff. You have to protect yourself and your finances. Personally when I was home I mostly did the cleaning ect but some days I got tired and couldn't do it all because I was exhausted. And so my husband would start complaining about how the house was a mess. So if be there cooking dinner or feeding the baby and i'd say ok so if it's so bad pick up a broom im obviously busy. It's so weird that your other half has been expecting you to take care of him all the time while still not even paying half the finances. no no no. Does he even know how much the stuff for baby costs ? Maybe it would help either circle on the bills and add up the stuff for baby, or have a credit card just for baby stuff so he's aware. Also if I were you i'd look up the cost of daycare in the area and make him aware that that's what you're staving by being home. so really all these months you've been laying all this $$ you've been doing TRIPPLE duty.
No your not wrong at all
