Noelle's Language development

Noelle's language skills are developing rapidly. She is making more and more complete sentences. And I am so happy about it. But at the same time it makes me a little sad. Why? Because she just isn't learning English. Her thinking is in Japanese. When she does speak English it is normally English words in Japanese sentences or in Japanese grammar patterns. Last night she said "hotです". Mixing the Japanese verb "desu" with the English adjective "hot" to make the sentence, "It's hot."
