Woke up at 4AM, took 2 hours to get back to sleep.
School had a graduation and 1/6 party in the morning so mom joined Boom. Boom cried a bit when teacher carried, but fell asleep in teacher's arms while watching the show although it was very noisy and hot. Probably tired from lack of sleep. Boom received a gift package from school: books, uniform, crackers.
Was happy and behaved well in the evening at home.
