36 months

Xander loves washing up, putting away folded clothes and towels and most recently is quite taken with using our camera to take pics of Cynthia (you can see his 2nd ever effort on her post this week). Xander enjoyed having Cynthia along at daycare for her first day last week, he even gets cranky with me when I try to pick her up to give her a bottle while they are playing. So yes, they get along really well... but I'm sure give it a few years and all of this will change.
