How to Handle the First Week of School?

Next year, I have a kid starting primary school and another starting kindy. So now I have a headache wondering how I should handle the first week of school.

Hubby was telling me to just drop the boy in kindy and then accompany the girl for the first week. The reason is because the boy is very used to the kindy by now since he is always accompanying me to send and pick his sister there. Quite often, we would hang around there for quite a long time too, watching the kids practising for their concert, taking photographs etc so the school is not new to him.

However, it is HIS first time going to the kindy so I would like to accompany him the way I accompanied the girl to get him off to a good start. So I was thinking of letting him skip the first week (since its mostly a crying week ie the kids will be crying most of the time in kindy), then I can accompany the girl for the first week and accompany the boy for the second week.

But will this be fair to him? Will he miss out anything during the first week? (Apart from the crying). I really don't know what to do. What do you all think?
