My niece swallowed something!! Please read

Hi ladies!

My 16.5 month old niece was playing with/munching on a candy bracelet and undoubtedly swallowed the string! Should we head to urgent care? Should we wait a day or two to see if she poops it out? Any advice would be great!

Note- she eats any and all human food with no problems, just wondering since this is something that can’t really be broken down!

Thank you.
