Burnout is real and nobody warned me
Been a SAHD for 18 months and I'm fried. Like completely cooked. My oldest is 4, youngest is 15 months. I love them but I am bone-tired and tired of being touched and tired of making decisions and tired of being the default parent. Some days I fantasize about just leaving for an hour and sitting in a parking lot. I haven't been honest with my wife about how bad it is because I feel like I should be able to handle this. It's "just" two kids, right? But I'm barely making it to bedtime without snapping. Probably need to actually talk to her about this instead of white-knuckling it.
Look into mommy/daddy daycare swaps in your area. One afternoon a week where someone else watches them so you can literally just sit in silence. Not even do anything. Just exist without needing to be 'on' for two kids.
