Caden really likes an activity that is just hard enough to challenge him but not so hard that it frustrates him. That being said lacing beads can be pretty tricky. I made it easier for him but still challenging by using a pipe cleaner and these beads that are a bit larger (you might recognize them from the big busy book). It doesn't hurt that the beads are in fun shapes and brightly colored. This kept Caden busy for about 20 minutes! I really like to sit with him during these activities but he really seemed to be in the zone so I cleaned house:) I love when he gets really focused on something. It's one of the signs that I've chosen a good activity for him.
