Your baby will probably be able to roll over when he's about six months or seven months, when his neck and arm muscles are strong enough. Some babies manage to roll over as early as three months, but other babies take longer than seven months.
Your babyâs initial rolling over takes place during tummy times. These are the times when she lies flat on her belly and uses her arms to lift her head and shoulders off the floor. This move helps her strengthen the muscles she requires to use around.
