alijangra,
Quite wrong! If a young infant male develops a paraphimosis it most certainly IS an emergency as blood supply to the glans can be restricted, often resulting in an emergency circumcision. What happens at a GP's if you require immediate surgery? You get referred to A&E!!
As far as young children are concerned it's always better to go to A&E and if the matter is not too serious they can refer you back to your GP.
By the way mgba_78, how is the little chap? Hope he's ok.
