thought: Find something strenuous or stimulating for the youngest to do an hour before bedtime, could even be learning. Sometimes the right amount of exercise before bed wears them out enough to stay sleeping.

thought 2: noise maker, ocean sounds or rain playing in the room can keep them from popping out of light sleep when they hear sounds from the rest of the home.

Wife and I split AM/PM duties. I do 6am and drive the eldest to school, then come back and prep the youngest before I go to work. but my youngest is order than yours, that mercifully tends to improve with age.

It’s better if the house duties are shared as well, but some people have different situations. If your partner is able but won’t meet you in the middle, there’s counseling. What often bites you in the butt is if your partner is depressed. Depressed people fail to engage; it becomes almost contagious as you try to pick up the slack and fall to it yourself.

Finding a better job with less hours can be part of it. Sometimes you need to look outside your familiar area for work that pays better, that’s assuming you can afford to move or find a job willing to pay you to relocate. There’s also more WFH jobs out there than ever before.
