Exactly, there is no one-size-fits-all for kids. People keep asking me when I'll start my son for kindergarten, if I'll keep him back or not because he's a September baby. It's like they want me to decide right now, when I can't possibly imagine what he'll be ready for in 2 years. I do my best to do what is right for my son individually at the time, not what is 'the correct way' for a 'typical three-year-old.'
