How did the transition go?

My son will be starting daycare next week at just about 9.5 months and I'm getting pretty nervous. He has some stranger/separation anxiety but he often surprises me with just how adaptable he really is. I think I sometimes underestimate how well he can do without me

Anyway, my rational brain says the adjustment will be tough, but he's going to do great when he is used to it. My mommy brain is freaking out though.

So, any tips, stories, advice?
