Are we going to break up?

My partner was abit like this at one stage, wasn’t willing to let go of life before having kids and thinks we’re just on holiday without realising how hard it actually is to not only go through surgery but from being pregnant to then looking after a tiny human on no sleep, I think you need to have a serious conversation about what your feeling and how your day looks, if you need him to stay home and not go out, do not feel guilty for needing support!!! It’s clear there’s some form of resentment both sides but it’s better to address the issues sooner than later, here if you need to talk xxx

I am sorry that you are having to go through this especially whilst you are still recovering.
And no it is not a regular stage of parenting I’d say. It is his time now to care for you and your baby boy. You carried him for 9 months, it’s his time to bond, but he needs to do it in a safe manner and do his research on what baby boy needs.

My husband takes care of the diapers at night as I am doing the breastfeeding, he does sleep through the 4am wake but I don’t mind that as he gets up every other time.
If he was doing his jobs to keep you guys afloat that would maybe be a different situation.. but if it’s for his car I wouldn’t say it should be priority right now. You should be able to get plenty of rest and still need to take it easy physically aswell.

You have a full time x2 job. He’s not valuing you or supporting you enough. Not sure your ages maybe he’s young and doesn’t understand how this works?

So I'm only going to tackle the second issue, because I really don't have any good advice for the first issue.

You guys are going to parent differently, and what works for one parent doesn't always work for the other. So yes, he should be allowed to have some time for trial and error to see what works for him and the baby. As long as he's not being unsafe, then he should be allowed to figure out how parenting works for him. My husband and I parent differently in most aspects- what works for him and our kids is not the same as what works for me and our kids. No one is born being a universally good parent overnight, if he's not given the opportunity to learn then he's never going to develop comfort and skill while caring for the baby. 16 days is so new, you're both still learning- you just have to remember that there are many "right" ways to accomplish the same task. ❤️

I definitely felt similarly during my 1st. What you feeling is valid. There are a lot of changes that happened so fast. Not only to you but also with your partner.
With the baby cry male don't pick it up as much as females do. Part of nature thing and what not. He might be trying to work more to make up for lack of income. Have you talk to him about why he started to pick up side job?
Remember you guys are a team. Everything else could be the enemies. Often time i snap at my partner and say back latter hay I wasn't mad you just the situation. It easier to snap at people we feel safe and comfortable at.
