We held both of our kids back—in preschool. Both were born in November and bottom 5% for height & weight. It was a tough issue for S because he was very precocious and there was some concern he’d be bored and he a behavioral problem. We still wanted to give him time to learn social skills. The pediatrician, preschool teacher and preschool director were all unanimous and we have no regrets. Because we held S back, we held D back too, so they’d stay 2 grades apart. It was good for her to grow intellectually as her older brother cast a big shadow, reading before he started preschool, etc.
If we hadn’t held them back in preschool, any time a person is going into a new environment, there is an opportunity to re-evaluate. Now sounds like a good time to give it some deep thinking.
