My DD made the cut off date by 12 days.. so we sent her... she was still 4 when she started KG and turned 5 that month. She was always the youngest in her class... the 1st year it really wasn't a problem, and we thought how lucky we were that she made the cut off, and we saved a whole year's worth of day care... when she started 1st grade is when we noticed she was struggling with many basics that we never noticed before.. It was like she had dyslexia.. writing letters backwards, and from the wrong side of the paper. etc... example... the word "look" was kool to her... In anycase... she got some extra reading support, and we were told that she was on level with the rest of her class.... but I still think she struggles. She is in 4th grade now, and I just had a conversation with dd's teacher and was told they didn't think she could read an analog clock either.
... so... bottom line.. go with your gut... At this point, I would hate to keep her back after being with friends for 4 years... but maybe you could always start with the kindergarten.. andnear the end of the 1st year, talk to the teacher and decide if they feel if he's ready to move on to 1st grade.. or maybe just do KG again... Say... yes, we know he's a wonderful kid, but is he ready to move on academically, socially. I wish we had that conversation with our KG teacher. The trouble with my DD is she gets by a lot on her "charm" personality,,,, hopefully it will get her through life
.... Now.... on the otherhand... I have another DD who also went to KG on the early side and she's doing great... it's just a matter of their personalities I think. One is more serious about school, where the other who just made the cut off isn't. I have a DS starting KG this september... I will definitely be careful about pushing him to 1st grade if he's not ready... I would rather keep him in KG 2 years,,, afterall, how much different is KG than the preschool?
