Advice for change of command (spouse)

Hi! My (29F) spouse is a Captain (29M) and soon to be completing change of command in April. I’m looking for “today’s age” advice, tips, what you wish you did type information. I know (back in the day) it was the expectation the spouse would be involved, and it was almost seen as a job. Up until this point I have kept my distance as I’ve had a full time career and been raising our toddler. This is an important turning point in his career, mine has taken a bit of a back seat so I am more available. I want to make a good impression to the fellow soldiers and be a united front with him. And support him best I am able too!

Thanks :)
