From a young age, both of my children have been really good with a hula hoop. Jay and I passed on our round shelf butts, so I think the kids are genetically pre-disposed to being good at keeping the hoop above the waistline.
Lately it is the girl's thing. The other night around 11 PM I went into her room to investigate a noise and found her, half naked and doing the hula. The noise I had been hearing was the swish swish of the hoop.
I suppose it says something about my parenting that my six year old is even up at 11 PM in the first place. During the summer months, I have a really hard time being consistent about bedtime. As long as both kids are at home and safe, I don't care what time they fall out or what part of the house they're in when they do it. So yeah, work that hula hoop all night long, just don't bother mommy when she's watching her crime stories.
