Umbilical cord??


My son is 11 days old and an edged of his cord kind of lifted and it’s freaking me out 😰😰😰 I know it should come off soon but with my first it was just in his diaper one day I don’t remember it ever being loose. I’m just really worried that maybe his shirt pulled on it or something while I was changing him and that it’s too early ☹️☹️☹️☹️ how old are yours and what are their cords looking like or how did they come off?
