hair tourniquet

So while changing my 3 month old baby I noticed something was wrong with her toe with looking closer I realized she had a piece of hair wrapped around her toe !!! My husband and i immediately unraveled the hair but her toe was still all swollen and red we took her to the pediatric urgent care where they said tho happens more then people think and it has the potential to be very dangerous ! As of right now we just need to kee an eye on it for any changes in the toe ! Please mommies look out for those stray hair in your babies socks !
