15 month old... throws fits

Ashley

We have a 15 month year old and he has started to throw fits. Example: he is drinking milk and it runs out he will freak out, in the bath and we turn the water off) little things.... we tell him no and he just laughs at us.... I know he might not understand fully yet but I just don't want to create a terror of a child!! Anyone else have this happening or happen?! Help please!! :)
