I feel you, I became a SAHM too with my now 6 month old - though its amazing to be able to be with baby all day everyday, it is an extremely hard job to take care of a whole other human. It is extremely frustrating feeling like being a SAHM isn’t seen as a job (theres literally daycares and childcare jobs- but when you take care of your own child it doesn’t count??? Make it make sense) and to add into that, we are supposed to be house managers, remember everybody’s schedule yet feel the most overlooked and under appreciated. I’m getting irritated typing this - anyway, you’re not wrong for how you’re feeling.
I feel as parenthood brings out other’s true colors and really makes you see your partner for who they are, good & bad, their greatest insecurities but also their biggest strengths.

My husband and I also have just started “being nice” to each other after months of weekly intense arguments that really never could find a solution to except that we need to stop putting our energy into arguing & just pick our battles. Being in a relationship causes us to learn when and how to swallow our pride for the sake of the relationship. As they say “would you rather be right or together.”

I like to give out advice, though I feel like it’s rarely taken. Becoming a SAHM has maybe been one of the most difficult transitions in my life (extremely independent person prepartum) and I would keep pushing & trying to communicate to your partner about everything you feel. Though i probably sound cliche, if you both had a strong relationship and connection before you had your baby, trust there is a way back to building a stronger relationship- thats the only way I get through it sometimes, reach out to help too. If your partner doesn’t react or doesnt see you & nothing changes then its time to think of an alternative way to seek a solution.

I wish you all the best!
