Also, like, adult humans don’t do so good if they only get to sleep for an hour or two at a time. I don’t have kids but I have a puppy and my mental health improved 10x when he stopped waking up every night because he needed to pee. Just going from two 4-hour blocks of sleep to one 8-hour block.
Then he hit puppy adolescence and had a massive sleep regression and I was getting an hour or two of sleep at a time between SCREAMING PUPPY INTERLUDES and promptly lost my fucking mind. I gave up on crating him because I needed the sleep.
