Is 14 months too young? My DS who is usually the sunniest natured boy in the world has started going into complete meltdown if he's upset - kicking, screaming, flailing about and not very easily calmed at all - which is totally out of character. He normally only cries if there's something wrong (ie hungry/tired/pooey bum). Is he ill or just having a tantrum? Surely he's a bit young?
