Floor-dropping tantrums at five are not OK. My son is five and if he tried that his bottom would be stinging and he'd be in bed early every night for a week NO playing before-hand, no favorite snack treats in the afternoons, etc. If he did it again within that day or week: Same sequence each time and also removing favorite items each time. He doesn't need to cope, he needs to behave. He's old enough not to do that if you don't allow it unless he's got a medical disorder. Be firm! Warn him in advance what will happen if he tries that. SWOOP the moment he does with one final warning and if he proceeds for even two seconds longer: Boom. Consequences activated. Keep calm and do not allow. And yelling at you not to say stuff? No. Same deal. Explain and enforce.
