We don't see our 2 year old GS as often as we'd like, due to their work commitments, ours and theirs busy lives etc, which I completely understand. However, we've just had a weekend with him, + his mum and dad, at our house and it was wonderful. We all met at a local Air museum, as he loves planes at the moment, so there was 'something to do' initially. At home we (and hopefully he) were just happy to potter around - looking at the garden, playing with a few bits and pieces we'd bought from the Charity Shop and acquired from relatives, doing chores etc... incredible how fascinating emptying the washing machine and getting the washing in can be when you're two!

I think my point is that if we want to see our GCs (us GPs I mean) we have to make a bit of an effort. I was careful though not to overwhelm him and to let him spend a bit of time just being a two year old and, yes that meant in front of CBeebies sometimes. It didn't take much effort either.
However, I don't post on here and especially on FB how much I miss seeing him and/or how cute/loveable he is, although he is, of course! From the Mumsnet posts it seems that some GPs, usually the ones who are uninterested in real life, do just that. Interesting that. Hmmm...
