Congrats!
When my daughter booked their Holiday shoot two months ago, they also sent me a list of what felt like TONS of things! Except my list didn't clarify not to go out an buy the stuff you didn't have. I happened to talk to someone from production (who called at 10:45pm) :O the night before and they told me not to go buy anything. So I showed up the day of the shoot with the items I already had (boots, sneakers, mary janes, belts, every color sock etc.) and I see all these Moms with Target bags full of new stuff!
BTW they had everything there in Wardrobe anyway and as far as I know, nobody needed the things they brought along. Bizarre!
Have fun! When my DD shot, they had a baby wrangler they flew in from NY who is a crack up she had the kids laughing non stop! My DD had such a great time!
