Gave my almost 6-year-old melatonin instead of her vitamin by mistake

Mommy failure...

I had a brain fart and instead of giving my kid her daily vitamin I have her melatonin this morning. I know it won't hurt her but I still feel bad. She's been whining ALL DAY and I finally was just able to rock her to sleep.

On the plus side this is the first time in forever she's let me rock her to sleep like this. She's almost 6 and going to kindergarten so it may even be the last 😭❤️
