As long as you don’t eat your daughter it’s OK, Kylie.
About two years ago I developed the same addiction to whipped cream. It was after I discovered that you can buy it in spray bottles. Those have probably been around for decades, but I’m a bit slow to notice such things. Anything.
So, my wife and I started to put whipped cream on anything that seemed to be a perfect match. Strawberries, whatever. Only steaks and chicken legs didn’t make it on that lest.
But we grew out of that addiction because we discovered that the needle on the bathroom scale started to move in the wrong direction. I also remembered my mother’s cousin. She had a serious cream addiction. Cheesecake without cream? Unfit for human consumption. And she had the figure, and the diabetes, to show for it (but still survived into her late 80s).
So, I’m pretty sure you and your daughter will grow out of it, too. But enjoy it while it lasts. Mankind is capable of worse sins than that.
