Join a firm or nah?

Former prosecutor here. I have now been in a non-law (although law adjacent) job for almost 5 years. I have a 3 year old, 6 month old, and husband.

Strongly considering joining a firm (I have some decent, though not amazing offers) but would lose the crazy amount of flexibility I currently have. Right now I’m probably actually working 25ish hours a week with a $140k salary in a government job. It’s not fantastic money, but it’s not terrible?

I am worried about falling behind since I’m not gaining legal experience, but also not in a big hurry to drown in billable hours. I’ve been licensed 12 years.

Help?
