It is certainly possible that a 2-month-old could roll over but it’s unlikely that a 2-month-old baby would have the necessary muscle development and strength required to roll over. Typically, babies will start to learn how to roll over at around 5 months of age. But, it’s a good idea to be vigilant with newborns under 5 months of age too. Babies can learn to roll fairly quickly and that can rapidly become dangerous if your little one is left unattended on a high surface like a changing table. So, be sure to keep an eye on your baby as they become stronger and more mobile to avoid any accidents.
