I am sorry for your loss .

I remember going to my Great Nans funeral when I was about 7, I do have small memories from the funeral but nothing negative/bad. We did see alot of Great Nan so we were kind of close.

I also went to my Grandads funeral when I was about 10, I do not remember alot about it, but I wasn't so close to him.

Sorry, not sure if I have been any help.

Just to add, if it were me I would take my kids, but as I said that is just me.
