i guess it takes time, to facilitate your child's english, you can show her educational DVD and watch with her and explain to her.... i think kids can pick up english very quickly as their learning skill is higher than we can imagine!
she started her N1 in a very normal kg (assume zero english).i play Barney, Patrick n friends, olive the rhymes, etc.... english cantoon for her almost everyday. But she cry everyday when you walk into the school, it last for half months. This situation make me headache.
It won't take long. You will then find that that speaking English during dreams. It happened to both my daughter and son. No need to worry about. They are much clever than we thought. Learning any languages when they are young.
