Where do you live that daycare for 2 kids costs more than one full-time salary?
If you both are making FAANG comp sure, keep working. If your spouse is a teacher? Maybe not.
For people who already own their own home, though, it's a pretty attractive living if you like kids. Most of the home daycares we looked at are run by people who bought ~10-15 years ago, and they make a very good living, and oftentimes have the house fully paid off. Either that or they bought recently but are pooling resources from multiple family members to afford the house, and then have them helping out with the childcare.
