It is fairly common for babies to be sick. Babies often vomit when they swallow air during feeding. This is completely normal and will usually stop after the first few months. Making sure that your baby is in a good position when feeding and winding your baby properly afterwards will help to keep vomiting to a minimum.
However, persistent vomiting can sometimes be a sign of something more serious. The most common cause in both children and babies is gastroenteritis. This is an infection of the gut usually caused by a virus or bacteria and is unusual in breastfed babies. It also causes diarrhoea. Your child's immune system will usually fight off the infection after a few days.
