A. It's common for babies to experiment with different movements, including rolling over, at various stages of development. If your three-month-old baby briefly rolled onto her tummy but has stopped, it's not necessarily a cause for concern. Babies may pause or regress in certain skills before mastering them. However, if you have any concerns about your baby's development or if she seems uncomfortable or distressed, it's always best to consult with your pediatrician for reassurance and guidance.
