Gift from baby to older siblings

Steph
So I was told to get a gift for each if my stepkids (9f and 13m) from the baby. To give it to them after baby is born and they get to see him for the first time. I have a limited budget and zero ideas on what to get them. The older siblings will be given a chance to buy something for their baby brother as well, but my biggest concern is getting them something. 
My stepkids and I have had a rough couple of weeks between dr appts, L&D overnight stays due to preterm labor, moving their rooms around to make a nursery and getting adjusted to living with dad and I again. We have rules and chores and bio-mom doesn't. 
I want the gifts to be meaningful and special. Any suggestions would be appreciated.
