Hi, I've just joined too, my daughter is 4.5 and has had b_phobia
possibly forever - we only recognized it at around 18 months to 2, but
I suspect it was there earlier.
She will certainly not wear clothes with bs and also will avoid people
wearing them, which is much harder to deal with, having social
consequences at an age when children are trying to make friends.
I am finally accepting the seriousness of this problem and glad to
talk with anyone about it.
