I am really concerned about my baby’s physical development. He is 4 months and 12 days, but he won't roll over. Everybody tells me that by now he should be doing so. He is almost 20 pounds. Is this something I should be concerned about? Or is it still too soon for him to roll over. Anything I could do to help?
