девы,
ВАш спор неплодотворен в даной ситуации

Если вопрос ко мне, тоя руководствуюсь тем, что мой ребенок гений гениальных родителей а также его желанием и интересом. Она уже потеряла , кстати, интерес к русскому алфавиту. На 2,5 мы и так много знаем для этого возраста))

совершенно с Вами не согласна, но спорить не буду

In studies of bilingual language acquisition, code-mixing refers to a developmental stage during which children mix elements of more than one language. Nearly all bilingual children go through a period in which they move from one language to another without apparent discrimination.[5] This differs from code-switching, which is understood as the socially and grammatically appropriate use of multiple varieties.

Beginning at the babbling stage, young children in bilingual or multilingual environments produce utterances that combine elements of both (or all) of their developing languages. Some linguists suggest that this code-mixing reflects a lack of control or ability to differentiate the languages. Others argue that it is a product of limited vocabulary; very young children may know a word in one language but not in another. More recent studies argue that this early code-mixing is a demonstration of a developing ability to code-switch in socially appropriate ways.
