End of week 1 for new boy..looking for input please!

I would probably give it another week before making any decisions on what you believe to be developmental delays, versus him just getting used to you and the daycare.

But I don't think it is too early to tell grandma that you are going to be working on making him more independent - practicing dressing himself, speaking in more complete sentences, etc. And that to make the best progress you ask that they do so at home as well.
