Melatonin gummies

My mom had bought me some after talking on the phone with her and telling her how exhausted I am between no sleep, work/life in general and my toddler. I joked telling her that at least I’m preparing for the sleepless nights of a newborn again. But out of the kindness of her heart, she went and bought me some sleep gummies!! I’m just not sure if it’s safe. I sooo badly want to give it a try though, what have your doctors told you ladies about melatonin?
