Im wondering if I need to be separating my 1 and 2 year old right now for activities or playgroups? Or let them continue to hang out together? I only bring this up because my 1 year old seems to follow around his sister and maybe not try things on his own. If that makes sense. I just don't want to create habits or make him feel like he always needs to follow Zuma around. I overthinking this?

And I know they will be in separate things in the future, just trying to figure out if I should start now. They hang out with all the oldests friends because no one around us has younger kids. And they are in a gym class together.
