My LO doesn't walk consistently yet (even though she's 15 1/2 months!) so if I'm running to the grocery store or other errands and it's warm outside I don't always bother putting shoes on her. I know I'm not going to put her down to walk.... because she can't walk and she just takes them off in the car anyway.

DH thinks she's old enough that she should always have shoes on, but I'm just lazy I guess, and I don't think people are actually paying attention to her feet.
