We got my son (19 months when he became a big brother) a couple of puzzles that make noise, a mega blocks dump truck, a bg brother book and a big brother shirt. The dump truck and puzzles were a hit in the hospital.
big brother shirt and book and a guitar ditto pp about annoying but kept him busy! i also think getting them a camera since you will be taking lots of pictures of the new baby!
Re: Big brother gift for 21 month old?
We did a ride on toy and it kept her very occupied while I was on the couch with a newborn nursing.
That thing was so annoying but kept her very occupied
