We have a WhatsApp group for our whole extended family (my sister and me, my dh and her dwife and both our dss). Family members post occasionally with photographs of the dc on holiday, competing in sports or at prize giving and whatnot.
I prefer to use another one we have just for my dh, ds, dM and dF which we use much more frequently and share private jokes, gossip and chat. It's a lovely way for the five of us to keep in touch.
My dnephew was surprised to see this more close knit group in addition to the main group and said he felt left out. Am I unreasonable to think this is normal? He's 13 and a bit over sensitive as he's close to his grandparents.
