Although there is a wide range of ages at which babies stop burping, if your daughter is now 4 months old, and does fine without burping, then you likely can simply stop trying to burp her. It may be that she is just not swallowing much air as she eats anymore.
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.
