I've just seen the announcement that Matilda is touring the U.K. in late 2018, DS will be turning 4 in October 2018, so depending the date the show is performing in my city it will be just before or just after his birthday and I thought it would make as a nice thing to do for him, as well as the fact I'd love to see the show too.
AIBU taking a child of that age to watch a theatre show? I've only ever been to see Dirty Dancing and Grease (when I was in school) so I'm not really sure as to what age is too young?
