No, it doesn't make sense to spend lots of high-value human attention on small children. For a pretty huge part of the day, small children are better off exploring the world on their own, and making social connections on their own.

Again: once your kid turns 5 (4, if you're rich and you send your kid to private all-day preschool), you're generally sending them somewhere where one adult will watch as many as 30 kids concurrently, all the while educating them to the point where they can creditably pass standardized tests. That's a harder job than just making sure kids are happy and engaged, and yet we pay far less for it than we do for child care.
Child care is a huge part of why people get crappier jobs than they might. You can't go back to school if you have no savings and need to pay at least $15/hr for child care; in fact, you can't even speculatively take a lower-paying job for career advancement if that job doesn't pay enough to offset child care.
