I guess that IS the age isn't it?! My niece is playful but is not all over the place. Maybe it's just a matter of time though till she's comfortable on her feet!
Art stuff is fun, that's the kind of thing Luke might enjoy making for her out of some of his papers, etc too. I also like the musical instrument idea!
It's so funny, it was barely more than a year ago when Luke was that age, yet I can't even remember what he was doing then!!!!
