Re late speech, a BiL of mine barely uttered at all until he was 3. My MiL told me she’d been getting very worried, but once he started....
He eventually won a scholarship to Cambridge and later went to work in Paris. Now completely bilingual.
Might add that when we lived in the Middle East, there were a number of mixed-nationality families. I knew personally of two where the children grew up with 3 languages - Greek speaking father and German speaking mother, who spoke to each other in English - and to the child in their mother tongue.
The children obviously became most proficient in the language used at school (English or Greek - there was a Greek-speaking school on our compound) but would happily converse in the other two.
Such a wonderful advantage for them, I always thought. At the toddler stage they would sometimes muddle them up, but they were sorted out eventually.
