my boy is 4 years old, now he became very naughtt, very mischeavous, say no to everything, doing tantrums, showing a lot of anger with teeth tricklering, what to do, what supplement should I give

A. Hello mama No need to give any supplements for this behaviour. This is common behaviour among kids and needs to be handled with love and patience. Secondly when the kid throw tantrums no need to give importance to that. As this is just done to gain importance. try to distract the child when doing so.
