Moms who do Santa what time do y'all set everything up?

What time does your kids goto sleep on Christmas eve? What time does Santa usually come by? What time does your child usually wake up on Christmas morning?

Mine haven't been going to sleep until 12am-1 am and if my oldest goes to sleep "early" she wakes up at 4 am ready to start her day.. But if she goes to sleep late she usually sleeps till 9:30.. Hoping to get them in bed by 9 tonight but so worried she will be up at 3 ready to play with her new stuff. I am excited to but didn't goto sleep till 3 am last night because "her elf" decorated whole living room in Christmas decorations for her to wake up to and then I was up at 7 am and have been cooking all day. This Momma is tired!

Edit: they are 3 and 7 months. The 7 month old has trouble falling asleep without me and wakes to nurse. The 3 year old gets in bed at 8 every night and is in and out of bed with every excuse in the book to get up (hungry, want to cuddle, thirsty etc) and sent right back to bed and lays there but rarely falls asleep before midnight.
