A bit of an odd one sorry. After a friend was laughing that her new baby has constant erections (often before weeing on her!) I realised I don't think I've ever seen my three year old or indeed my 8 month old with an erection. Obviously who knows what might be happening down there throughout the day but it does strike me as odd. Something to be concerned about? Can't face the GP. Given neither of my boys do maybe it's okay
