Seconding it's time to avoid social situations with family.
Despite my folks being cool, I had to avoid going out with them for a while pre-T. There was an awkward time where they still saw me as not passing, while I was passing to most strangers.
They didn't feel comfortable / couldn't get their head around using the right pronouns when they were convinced I still looked like a girl to other people. I couldn't keep my temper in check when I was outed by people I really didn't want to be angry at.
At the time, they were also still quite emotionally raw from my coming out.
Eventually we had a little chat and came to the conclusion that for the time it'd be best just to refer to me in a neutral manner ("this is my kid" or "they") until the other party gave us a clue how they'd read me (and then run with that).
Worked well. Eventually they started using the right pronouns and all that on their own - especially once I went on T, my voice broke, and I've started growing an unmistakably male amount of facial hair

Now they're keeping each other in check and trying really hard to get everything right - 'cause they've admitted that now they'll look silly if they slip up!
