Selective fluency - is it a thing?

Question

I speak 4 languages, and I have the least exposure to my native language, since I have never lived in the region where it's spoken. My only exposure to it is speaking to my parents, and some TV. I grew up speaking 1 other language as an infant, and 2 more since Kindergarten. I'm quite fluent in these 3 languages, as I have a lot of exposure. (National language, regional language, and English)

Now, I speak my native language very fluently with my parents and a handful of other people. I can start speaking fast and effortlessly off the bat, like with the other 3 languages. But if any other person starts conversing with me in my native tongue, I'm caught off guard. I stammer, fumble a lot for the right words, don't get the pronunciation right, and take help of English a lot. It takes me anywhere between 2 days (if I'm in constant company of that person) and never to start speaking fluently like I do with my parents.

I feel like I'm selectively fluent, like selective mutism, although google doesn't have any results for it. Is this a thing? Is there a proper term for it?

P.S: This handful of people I mention have been around on and off since my childhood. They're uncles and aunts and cousins.

@bytebuster Except I am still fluent, but only with a handful of people, I wonder why that is! — insanity, Jul 11 '18 at 13:43
@insanity In my case: practise practise practise, spending a lot of time outside my comfort zone. Moving to the country where my "uncomfortable" language was spoken ... Plus I had some confidence problems in those days which I am glad to say are past now. — Omar and Lorraine, Jul 12 '18 at 10:52

One of my MA instructors, Alex Ho-Cheung Leung, has researched this question with regard to phonology. He says that speakers of 'heritage languages' (e.g. spoken within the family but in the wider enviornment of a different language) may develop less robust phonology because they only hear a limited number of variants of each sound. That makes them less flexible when exposed to other variants. Seems similar to your case.

I'd expect it to be the same in terms of vocab and perhaps even grammar. – curiousdannii Aug 24 '19 at 10:34
