Baby smells like McDonald's

I know this sounds insane, but my 3 month old daughter gets this distinct McDonalds French fry like scent to her and I don't understand why. Everyone I tell looks at me like I'm nuts. My daughter took a bath last night and this morning my friend commented that she smells like McDonald's French fries. I have never mentioned the smell to her. At least I know I'm not having olfactory hallucinations now. Anyone else experience this or heard about it?
