Recommendation mashup near Polanco (mid May)?

Hello! I will be in Polanco with my friend and her lovable 1.5 year old daughter. I am ISO activities like child friendly museums and parks and restaurants where we can go and with her daughter.

We (30sF) might also be able to sneak away for a day and I would LOVE to treat my friend to a massage, spa experience (I am considering Hela Spa at Brick House), or anything on a rooftop. Please share your favorite massages, day spas, bars, and restaurants.

For me, I would love any kind of LOCAL craft fair, street vendors, night markets, and hole in the wall gems.

I know this is a mixed bag haha but any insight would be helpful. Thank you!
