My son skipped 2nd grade partway through the year and it was not without some social struggles. First he got picked on by a child much bigger than him and my son is not very assertive. Then my son seems to recognize the 'cool' popular, athletic kids and seeks out friendships with them. He tries to be one of them and it's hard for me to witness because he is not an athletically-talented kid, especially compared with a bunch of much bigger kids- they are not mean though and seem ok with him.
This is very astute of him.
