Does learning more than one language at an early age confuse children?
No. In the past, parents were discouraged from speaking more than one language to a child for fear of confusing him or her (not only in Wales - it also happened in many other countries, such as America). However, it has long since been proved that the earlier a child is exposed to a second language, the more easily they will pick it up.
A small child may hop from one language to the other and seem not to know which is which at times, and will certainly know words in one which they don't in the other - but the gaps will fill themselves naturally as time goes by. Don't miss the opportunity to give your child the gift of bilingualism!
