I'm not really sure that's how it ends up working in reality though if you have exposure to English through school or childcare. We taught our kid Chinese first. He's now 2, almost 3, but he's equally good in both languages, maybe a little better in English at this point since he goes to school every day. So by 3 years old he's just as good or better than his peers in English but also is a native speaker in another language. I can see how a parent might think they are putting their kid at a disadvantage by not concentrating on English but language just comes so naturally to these young children.
