Kavi discovered the hat…
Kavi discovered the hat game last Christmas -- put on a hat, pull it over her face, bewilder the grown-ups who now mysteriously cannot find Kavya, pull off the hat and laugh uproariously. Months later, the hat game still reliably delights her.
My husband and I somewhat regularly visit some friends of ours with two small children. When the younger child was still an infant and somewhat skeptical of strangers, I started playing that game with him, and he loved it; two years later, he *still* loves it. 🙂
