Thanks for all your replies!

I didn't realise how common it was to wait! It's good to hear that others are thinking the same things. I'm so glad I asked now, because I was actually in the process of looking at kinders and filling out applications for 3yo next year.

I am now convinced to hold him back. DP has wanted to anyway, but it was the other mums I know that have confused me. In my mothers group and playgroup, the kids are also feb babies and their mothers don't want to wait an extra year because they fear their children will be the eldest and stick out like a sore thumb - physically and intellectually. They are mostly girls though, so maybe it's different? It's a shame that DS's play mates are all going to go off to school before him though.

Onyx, your DS sounds like an independent and confident little boy! The complete opposite of mine! Haha. You're right though, that it really depends on the individual, and if he flourishes in the next year or 2, I'll reconsider.

DS is only 2, but I know that he is very shy and reserved (like me) and he is very soft spoken as well. He is super clingy and whiney and it's "mummy this, mummy that". We do playgroup and gymbaroo and I can tell from observing the others that are his age, that he is no where near as mature as them socially/emotionally. I wonder if he will change dramatically in the next year? But I doubt it. He has also never been away from me so I think 3 yo kinder next year would probably stress him out too much.

It's hard to imagine, but when DS is in year 12 he will be 18 at the beginning of the year so I hope he doesn't get carried away with being "legal" and forget about school!
