There is a sweet 11yo girl who is the sister of a boy on my son’s baseball team. She always offers to play games with the little siblings and keep them occupied.
IME elementary age kids will generally play with whoever is available. And my DD and her friends (6-7yos) LOVE babies and will dote on any of their friends’ baby siblings whenever they have the chance.
