He is 36 months old ( He stepped in to his 4th year)

Yesterday on May 26, 2013 (Jesth 12, 2070) our son was 36 months old. Actually he stepped in to his 4th year. (But according to moon calendar, his birthday day was on may 24, 2013 or Jesth 10, 2070)
He is 3 ft and half inch tall and .. kg in weight. This month we celebrated his 4th birthday. We had a nice time together.
He has learned having food all by himself. He can go up and down the stairs without our support. He enjoys playing in rain and water a lot.
He enjoys going to school and has started tracing letters, and coloring different pictures. But he doesn't enjoy doing his homework.
Moreover he has become a grouchy guy now a days. He wants to fulfill his each and every wishes, otherwise he behaves like a little monkey. He quarrels with his aunty a lot.
