I have two under 3. When we still had 1, my domestic supervisor, was really starting to climb and advance in her profession. She was stressed. Stressed as a wife, stressed as a mom, stressed at work. Couldn't nap when the kid did, because that was a critical two hours for her to finish a report, or send emails, ect. Which meant the kid, WAS GOING TO NAP, wether he wanted to or not. But then at the same time, the kid ruled the house. It took a bit for her to acknowledge my strategy, of that's what he wants, but he's two years old, so too bad. We have different parenting styles. Mine seems to conflict with whatever social influencer, or webcast she's listened to. I however, am going to raise MY kid, the way I think works best for HIM. Everyone is different, and I'm not going to let an expert thats never interacted with my son, influence how I am going to interact with him. I'm just trying to do the best I can, but as I type this, I know I could do more, but I need some "ME" time, for my own emotional stability. The wife needs her time as well.
Everything takes longer with him involved, but I know it's really helping the wife, and he loves it. So instead of it taking twice as long, I realize, that I'm doing two things at once, and that helps me cope with the fact that everything is slower, or more difficult to do. I'll try to plan my projects that I can do with him, around times he's awake, and the ones I can't do with him, after he goes to bed, or he spends time with mom.
My kid loves being outside. He essentially covers the entirety of the 5 acres he has access to, and is completely self entertained, unless mom/dad are doing something cool. Inside the house, he's a toddlerist, and it's really difficult to get him to self-entertain. We always tried to keep screen time to a minimum, but now with 2 kids, we definitely use it as a crutch. But he loves helping and being involved, so anything we can do to make him part of the activity, really helps.
Parenting is tough. In my opinion, it never gets easier, it just gets different. The times I'm most frustrated with my son, are when I'm trying to do something "I want to do" and he just wants attention. Usually, whatever it is that "I want to do" can wait, and I still have trouble acknowledging that. He's constantly testing the boundaries and limits, and now that he's a big brother, he's learning that he can get attention by acting out, or being naughty. We're all learning together as we go along, and I make mistakes, just do my best not to repeat them.
So back to my wife's career. My response sounds the same as yours. If you want to work, I support that, however you have an inability to say no, and I can see it's stressing you out. We would get a babysitter to come to the house, and I'm pretty confident, that after taxes, my wife was working for $2/hr, possibly -$2/hr. However, I acknowledged that it was important to her, and was a nice break from momming, so that continued until the third trimester of our second kid. I think she quickly realized how much happier she was - not working. And has said so, several times. But that's got to be her decision to make.
Compromise and communication. It's just what has to happen. Goodluck!
