Oh that’s a hard one.

Just with the negative responses from people, were they specific to your DD or did they just not like the idea of sending a 4.5 yo? If they were just generally negative then I would probably mostly disregard their opinions.

I’d be asking yourself these sort of questions: Can your DD wipe her own bum? Can she put a jumper on when she’s cold and take it off when she’s too hot? Can she ask for help if she needs it? Can she introduce herself to new people? Can she play nicely and make friends? Can she sit still and concentrate for at least a little while? Is she interested in going to school?

I would use these sort of questions/answers when making a decision. Every child is different and I have certainly seen children that are absolutely ready for school at 4.5. It just depends on the individual child.
