Hi there! If you're still looking for groups and activities, my son (8 months) and I have been getting out a lot with a group called "Hike it Baby." I am one of the Houston branch leads and we have walks and meetups all across the greater Houston area. It's really for anyone - moms, dads, baby sitters, grandparents, etc. With the hotter weather setting in, we've scheduled meetups at splash pads, walks in the morning and evening when it's a little cooler, and there are some weekend activities popping up as well. Hope to meet you soon!
I live in Katy, but there are walks scheduled all over Houston. Many of them are centrally-located, so you're in a great spot. There's a full calendar of events on Hike it Baby's website: click here.
