Umbilical cord stub still on 3weeks 2 days

Sarah • Mom to a toddler girl via ivf. Pregnant with baby number 2!

my baby girls stub is drying out and i haven’t touched it.. her pediatrician was going to add something to it but i told him i prefer it dry out and fall of naturally... it’s not infected or anything

but it’s still on there at 3 weeks 2 days is this normal? i heard it comes off 5-15 days after birth...
