Try to put yourself if in his shoes - now imagine being only 18 months old and not understanding what is going on. He is hurting, confused and needs his mommy. Your sleepless nights and exhausting days are just part of being his world and he totally needs you right now. Try to comfort him with lots of hugs and kisses whenever he needs it and muster up all of your patience - he is still a baby, after all. Get him some stickers and things to decorate his cast. Help him with the itches that come. Tell your doctor what is going on - they might have tips or be able to put him into a flexible cast soon. Just be there for him - this is a small drop in the bucket for what mothers do for their children - you'll both look back and laugh one day.
