A. “Babies might not roll over right at 6 months, but if you aren't seeing any attempts at movement, definitely discuss it with your pediatrician,” . “If your doctor thinks there may be a developmental delay, you'll be able to work together to figure out what the next steps should be, like physical therapy.”
