As far as toothcare goes, it is best to wean children off drinking milk from bottles or breastfeeding by the age of one. This is because the sucking and pooling effect of drinking milk in this way is a cause of tooth decay.
Never put your child to bed with a bottle of milk. Saliva flow is reduced when we sleep, so the mouth’s defence mechanism isn’t as effective at neutralising the acid formed when sugar in the milk is broken down.
Having a drink of milk before bed from a cup is fine as long as you make sure your child’s teeth are brushed afterwards.
A standard drinking cup is the best option as soon as toddlers are ready. In the meantime, cups with built-in straws are better than anything with a spout when giving them juice, as there is less contact with the teeth.
