Have either of the kids shown a passing interest in learning to woodwork? Obviously tons of safety precautions need to be taken (including potentially changing the nature of projects to do them more safely for kids), but maybe that's a way to at least get in the shop a bit, even if it's to make some simple hand-tool boxes out of scrap with a kiddo.

Edit to add: it's definitely tough to make as much time for hobbies as a parent, and I hope you're able to find some good shop time in the New Year!
