Back to work....Help!

Hi Everyone,
I have already put a similar thread in the wrong forum by mistake, so sorry for the repition, but I thought I'd put it in the right place as well.

I have been on mat leave since Dec '08 and am due to go back to work in just over one week. I have had a wonderful time at home with my son and have made some fantastic new friends who have also recently had babies. It is going to be tough to go back to work as most of my friends are still off.

I know it is going to be heart - wrenching leaving my son at nursery on his first day, but I don't want to spend it in floods of tears at work. Has anyone got any tips on how to cope with the first day? It must get easier with time...?

Thanks,
Canary.
