Were you close with your aunts/uncles?

So I'm heading into my mid 30s and though I'm realising kids may not be for me, I'm lucky to be the proud aunty of several young niece/nephews! I want to have a good relationship & sense of connection with them as they get older. The thing is, I rarely saw my aunts/uncles as a kid, and I barely know them as an adult... So I don't have a template for this!

Were you close with aunts and uncles growing up? Do you keep in touch with them as adults? How did they have a positive presence in your life?

For some extra context:

The niblings' ages range from 2-8 and right now I have good relationships with each of them through playing, reading to them etc... They're generally excited to see me but I'm very aware they're at an age that is easy to impress! I'd like to be someone they feel they can talk to when they're older, and I'd like to be a positive influence in their life overall. (And for my own sake of course, without kids of my own, I hope there'll be some nephews/nieces/grand nephews/grand nieces who maybe will give a shite when I kick the bucket!).
