My brother, sister and mother came to visit yesterday, went home again this morning. Mother and sister managed to be at least friendly to 11-mo DS (none of them like babies very much, fair enough, I can't expect them to feel any different about mine). Brother ignored him completely (didn't even say hello) and poor DS hasn't ever had to face that in his own house before, so looked really baffled and quite upset when he didn't get any response.
AIBU to say that when brother next comes round, he has to manage the minimal politeness to DS that he would to an adult he didn't much like, rather than blanking him completely, or am I being PFB about this?
