S.C.
there is book my sister recommended that she said was good on this I will find out name and get back to you. I also have a 3 yr old son born in may at this point I am leaning more towards holding him back, but I also may consider if I do hold him back listing him in home school and working with him then reevaluating whether he is ready to go to first grade or start in kindergarten. at that age it is really easy to home school you can also enroll in an affordable pre-k if you want at the same time like Pixies or somewhere, Boynton beach has a few that we did that we liked. maybe the one on one time that year will really get him going and you will feel like he is ready for first if not then he has gained great prep for kinder. If you need more info on any of this feel free to ask
