I admit that I’m excited for the sleepover stage. And I mean the innocent kind where little ones eat pretzels in sleeping bags – and don’t watch “Blame It On Rio” at a friend’s UES apartment. (Bad!) Smiling Planet, the originators of whimsical – chic tableware are about to launch this sweet, water-proof overnighter. It’s so cute that you can stuff it with animals when she’s not on a little adventure or simply hang it on the door knob. Smaller tikes can even take it to grandma’s. And nope! Raunchy ’80s movies not included.
