Is it selfish to not want my son to start school? My son is 3 and will start 4k next year. The thought of it depresses me. I've been a stay at home mom ever since I've had him and I just dont think i can part from him for that long; a few hours. I'm even thinking about letting him start school a year late. Help me, I can't go an hour without missing him and running back home to him.
