My husband spends a ton of time at the playground with our kids and swears he can tell the difference between moms and nannies and dads and mannies. When I asked how, he said it's obvious when you watch their interactions.
I'm not so sure I agree, but it did make me laugh when we saw a too perfectly primped woman pushing a double stroller with newborn twins in it and he declared "nanny." Then moments later, he called "mother" on a woman holding her tot sideways as she crossed the street. Do you think it's possible to call out parents from caretakers based on observations?
