Do your mom/mils take your LO to activities?

Now that ds is 15 months and the weather is finalllly starting to warm up a bit, I think I am going to ask her to take him to the library (and she already can't wait to take him to the park)...

There are gymboree classes she could take him to, too, but I feel like that might be too much at this point.

At least the park and library are with a few miles from her house. (I do worry about others driving LO, even though she has a few times before back/forth from our houses).
