Sorry to hear your sad news, but glad you got some lovely photos.
My nan died when Ruby was 4 weeks old and I didn't take her to the funeral (didn't want to have to take her out and miss the ceremony if she had started crying) but we took her to the wake after. However, had she been older, then I would have taken her, various cousins took their LOs (mainly due to having to travel from around the country and therefore not having anyone locally who wasn't at the funeral to look after them), but it added to the service in my opinion, as all the great grandchildren were mentioned and it was nice that they were there.
My lasting memory of nan's funeral was sitting on an aisle seat and watching a rice cake rolling along the aisle (from my cousin's 1 year old sitting a couple of rows behind me), which made us all laugh, had my nan been there she would have been the one laughing the loudest!
Good luck with whatever you choose to do x
