My kids are COLD?!

So when I wake up this morning and decide to make the kids yoghurt, strawberry, banana, milk & ice smoothies. They drink them all up quickly & ask for seconds. I have all the windows open in the house to bring in the cooler morning air. Then K complains about being COLD. I say no way, enjoy the cold. Its going to be hot real soon. And sure enough, its 9am & I'm ready to close up the house. Window, shades & all. We are about to head to the park! Have a great weekend.
