I run a paint night side gig and it goes well if people can come to my home, otherwise it is definitely tricky!
Anything you are passionate about? Maybe you can offer something from your home?
You can make a care.com profile and offer babysitting with your baby or also post it on community pages. Also check out rover and if you can get a few reoccurring people to pet sit you can make some good side gig money. I did both at the same time and made a living for a while.
I bartended when my partner had days off
I start network marketing/directselling when my little one was about 13months. Now 2 of them but I still enjoy it
