Same here, except I quit completely to stay home with our two kids. The decision was easy. One day when I was working remotely from home, the nanny rushed in carrying my 6 month old daughter. She was completely unresponsive, having her first of many febrile seizures. Eyes rolled back, body limp. We called 911. By the time they arrived she had mostly recovered, crying, but could respond to us. I quit a few months later.

She's now 5 and her brother is 7. They grow out of febrile seizures and luckily she hasn't had one now for about 2 years. Overall she had about half a dozen.

Besides that, the reason I also it is because if one day, my child is a drug addict, asshole, school shooter, or any other "failure" of sorts. If someone asks me if I did everything I could to prevent it. My answer will be yes, I gave it my all.

It seems in the US when people say I want to provide for my children, they mean money. But more money doesn't really help your kids, it helps you. What kids really need is people to provide time.
