Arguing

We have a 5 month old and obviously before he was born we were able to argue/have serious discussions no problem before he was born. But now he’s constantly around us and it sucks being angry/having serious difficult discussions and I obviously don’t want it to be around him but it’s hard in the heat of the moment. And I’m not talking about yelling, fighting etc since we haven’t had those types of disagreements in a while/ those rarely happen. I guess I just don’t understand how some parents get through those times. Ugh and I hate not having my own income, but right now I can’t, there is absolutely no time at the moment. Which puts me in a difficult/vulnerable position. My husband is pretty awesome and wouldn’t take advantage of that at all, but I’m just super independent when it comes to money. This is all just super new and difficult for me and I feel like he’s not being very sympathetic at the moment.
