My kids are 5 and 8. We live abroad. To avoid outing myself, I’ll change the languages used (apart from English). I speak English with them and my husband. English is their mother tongue. DH speaks German with them. School is also in German. However, we live in a bilingual place. A lot of DC’s friends have French as a mother tongue, so they hear it often and understand a little but can’t speak it. I speak French when out and about, and not German. So it’s a real mish mash of languages.
Their English grammar isn’t great, mainly past tense. I speak to the them exclusively in English. They watch English TV and films, and I read English books to them every day. So I’m not concerned about their exposure.
DC 8 mainly makes errors with irregular verbs- I drinked, I buyed, have you tooked etc.
DC 5 consistently says- did you gave, I didn’t said, did he ate etc.
I correct gently, for example ‘did he eat the chocolate? Yes he did’.
So my long-winded question is- are children in the UK making similar grammatical mistakes? I know my children will catch up, and they are lucky to have English as their mother tongue. I’m not worried about that at all. I am just curious if they are at a similar level to UK children or not. Is this a phase all English speaking children go through?
