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 baby may take you by surprise by suddenly getting the hang of rolling over. This is why it is so important never to leave your baby unattended when changing his nappy on a raised surface.
