Guidelines vary from country to country.
All babies are vulnerable to the germs that cause diarrhoea and vomiting, and so it is best to continue sterilising bottles and teats (and breast pump equipment) until your baby is one year old and has built up more resistance to bacteria generally. The recommended age for starting solids is now six months, and bowls, plates and spoons can generally be cleaned using your usual washing-up method from this age.
Cleaning your baby's bottles and teats in a dishwasher will not always heat them to the right temperature to kill off all known bugs, so it's generally still advisable to sterilise after washing. If you do want to rely on your dishwasher alone, it needs to be run on a hot programme at a minimum temperature of 80 degrees centigrade. The bottles then need be filled with feed straight away as the dishwasher will not leave them in a completely sterile condition.
It may seem pointless to sterilise feeding equipment when your baby is crawling around the floor and putting all sorts of things in his mouth, but the bugs that stick to milk curds can be dangerous. Your baby's immune system will grow stronger into the second year and he'll be able to combat infections more easily.
