Current advice to parents when their child swallows something like a LEGO head is to check the stool of the child until the object is found.

This small trial, in which 6 paediatric health professionals swallowed a LEGO head and searched their own stool until the object was found, suggests that we don't need to ask parents to search the stoll.

I didnt get it, what’s the point? The LEGO shouldn’t not be an issue even for toddler to pass. Assuming, it is not LEGO Duplo head.

Parents worry that it is a problem. Doctors tell parents that it's not a problem, and to just check the child's stool. That's unpleasant for parents to do, and probably isn't necessary because, as you said, it's not a problem.

but if you are a worried yet squeamish dad this study gives you a reason to hand the task on to your partner as women are apparently better at it!

i applaud the writers of this study for the addition of a little humour
