What can you do to calm a 5 1/2 mo. old baby who will cry incessantly unless being walked? I have 3 children and never dealt with a baby I couldn't calm and soothe. You worry so much today about vaccines and their possible connection with ADD and also Autism. I am talking about my youngest grandchild. Most of the time her mother cannot calm her either. She has never taken a pacifier and is stll breastfed but also supplemented with formula. Any calming tecniques would be greatly appreciated. Do you think she is spoiled?
