I love how Kate watches Suki -- she's really learning how to build some great structures of her own.
The thing about having three children so close together is that the milestones sometimes tumble one after the other. Right now Suki is learning to read and she's doing it the same way Grace did, with the fantastic Starfall site. Kate loves to watch her sister play and practice her beginning sounds, etc. too.
Such funny girls -- Kate's jumper is undone because they'd just been jumping around like kangaroos and this was the only way her penguin could be the baby joey.
