How can i keep a hospitalized toddler entertained?

It depends: It depends on the illness, if your child can get out of bed, and if your child is being isolated due to infection. Many children's hospitals have games and other activities for the kids. If your child is confined to bed for now, books, music, games, and craft projects can help. Talk with the hospital staff as well to find out what might be available- videos, visiting volunteers, etc.
