My mum was looking after. DS's today and DS2 got to the marble bag before she did. She is fairly certain he hasn't but can't be definite. Do I need to be worried?

Surely he would have choked? if he seems find in himself Id just see how it goes but if he seems off get him checked.

You need to check his poo (lovely) for it to reappear! It's usually passed without a problem but any tummy ache needs medical attention
