Follow the instructions on the bottle for your child's age, or check with your pharmacist, GP or health visitor. People put all sorts of things down to teething - rashes, crying, bad temper, runny noses, extra dirty nappies. But be careful not to explain away what might be the signs of illness by saying it's 'just teething'. Let your child see you brushing your teeth too. Cut down on sugar.
Sugar causes tooth decay.
It's not just the amount of sugar in sweet food and drinks that matters but, perhaps more importantly, how often there are sugary things in the mouth. This is why sweet drinks in a feeding bottle and lollipops are so bad. The teeth are bathed in sugar for quite a long time. From the time you start your baby on foods and drinks other than milk, avoid giving sweet things. Try to encourage savoury tastes.
