My native language is Russian and this is important in scope of the question: past tense verbs are gender-specific here, for example "I've made..." will be "Я сделал" if you are a boy and "Я сделала" if you are a girl.
So, I have a 2 year old son and he speaks really well for his age. But sometimes he uses the wrong form of verbs (as described above).
Should I be concerned and help him if he's confused about his gender or is it just a language issue?
Let me change the question a bit, so it might become more clear - Is this a grammar issue or a self-identification issue?
I have a feeling that this all sounds like I'd love him less if it's not a grammar issue - which is definitely not true.
