My unskipped-but-young-for-the-year DS hasn't really found close friends yet of any age, but seems to get on well with both classmates and much older children he meets through shared interests. And, come to that, younger children ditto. I have been worried about his social skills in the past (and when he was 4/5/6 this was sufficient reason not to skip), but not so much now (there are different reasons now!). I was surprised to overhear him talking very sensitively to a much older friend who was nervous about an upcoming event - but mostly this brought home to me how little I actually know about his social skills! He very clearly adapts to the company he's in now, so I think if he were skipped or double-skipped he'd now be fine with older friends. What I don't know is whether he'd then have closer friends than he does now with age mates. I rather doubt it.
