Oh I would certainly say so yes. A (18 year old) has developed really strong boundaries and is very adept and eloquent when it comes to expressing them. That also goes both ways, with a respect for others, for their boundaries, autonomy and personal space.

With this issue and others (eg. A has a really severely life threatening food allergy), I’ve actually found that the people I’ve had to struggle with the most have unfortunately been the ones closest to us. In-law grandparents have been a particular trial, though otherwise lovely people worth persevering with they (especially mother-in-law) have been consistently frustrating and hard work. I’m not convinced that they really ‘get it' even now. They most certainly consider me a bizarre and fussy person who is an intensely overprotective mother!

Definitely worth persevering, though you may need a wig at times to hide the fact that you spend so much time tearing your hair out in frustration.

A thanks me for my efforts. I would predict that your daughter will thank you too.
