How to handle this with our three year old? NC with grandparents

[OneDayMySleepWillCome]

We are No contact with dhs family. Have been since our 3 year old was about 6 months.
She had a friend round yesterday and they were talking about their grandparents (friend does 1 day a week with each set- calls one nana & the other grandma) DD just asked me why friend has 2 grandmas and she just has one. She wasn't sad at all or jealous or anything like that, just matter of fact.
I said 'why do you ask that?' And she replied 'And. Do cats talk?' Then wandered off! So I don't have to answer immediately.
I always knew we'd have to discuss it with her at somepoint so need to talk to DH tonight about what we say next time.
Does anyone have any thoughts? Or anyone been in a similar situation?

At that age, I'd just go down the route of "all families are different".

We went NC with DH's mum when DD was about 6 months old (total NC lasted 3 or 4 years and now DH has low contact - DD has never had a relationship with her).

DD is now a teenager and knows the reasons why and understands them. I've always been fairly open about stuff (in an age appropriate manner) and we never pretended that she didn't exist, but would just say that we didn't see her. Just answer questions honestly when they come up.

We were always open with DD - Granny and Aunty did something horrid - we no longer speak.

Sometimes people are not very nice so we don't see them, we have lots of friends.

Just be open - as they get older they can handle more information and may ask more questions, but be matter of fact.
It is a good life lesson:
you don't have to put up with being treated like crap, even if you are related to that person
some people are horrible, so concentrate on spending time with people who actually like you

I did the same with my daughter, told them my grandparents weren't my sort of people. As she got older and realised there were people in life she didn't dislike but didn't like too much easier, she rationalised it in the same way.

I had no contact with one of my grandparents. In the early days I wasn't bothered because I had another grandmother I totally loved. When I got older & more curious I was told 'she's not a very nice person'. The truth was pretty horrific and I'm confident it wouldn't have brought anything positive to my life having her in it. Don't miss her in the slightest.

We have some similar issues in our family. I have always been honest in an age appropriate way, and stressed it has nothing to do with the children.

It has opened up conversations about how far you are prepared to accept other people's bad behaviour, and that just because you're related you don't have to allow people to upset you. Our children are older than yours, but I've often used the analogy of how children play together at school, and when childhood friendships go wrong.

It's not nice to have to learn such a life lesson so young, but I think the alternative of secrets and "I'll tell you when you're older" is much worse, and potentially quite damaging.
