My son has been an absolute whirlwind for the past year and a half. He has ridiculously high energy and 5 or 6 people have suggested ADHD. He's loving, and kind, and I adore him, but I'm exhausted. He cried for an hour and a half last night because he wanted to have his own monster truck. Not tantruming but sobbing and needing hugs because he was distraught. He never stops running, cannot sit still for more than 30 seconds, and seems like he barely sleeps but still has tonnes of energy at 8pm. He has a great diet, great routine (bed bath and story same time every night, but wakes up very early). He just has so much energy to the point that people comment on it regularly. And is so sensitive, aka when something doesn't go his way or a project like lego isn't perfect he goes into meltdown mode and says he is rubbish (this is heartbreaking). Is this the same for other 4 year olds or is it not the norm?
