Stronger Mandarin Foundation

I guessed it's because Little Arielle's time spent with mama is longer, thus her foundation for Mandarin is stronger. Although, some people told me that it's good to be stronger in Mandarin as they will pick up English easier when they go to school. But, I am still worried that she will not be able to catch up.

Have tried my best to speak to her in English at all times and hope that she will not lose out in this area!
