Our son is 26 months old

Today on July 27, 2012 (Srawan 12, 2069) our son is 26 months old.
Physically he is 2 feet 4 and half inches tall but he is not gaining weight accordingly. He knows well about his bowel movement and tells us when he wants to go to the toilet. He is learning complicated works with his hands like opening the lid of the bottle, opening the door lock, etc. He is able to walk up in the stairs easily but need some support walking down on the stairs.
He has started using plural words like crows, cats etc. He enjoys playing with his elder brothers and sister. He seems to know about birthday and birthday cake.
He enjoys local festival Gai Jatra and specially watching "Lakhe"
This month we bought an i pad for him.  He enjoys it a lot. He plays different games. He names  picture of different animals, enjoys solving picture puzzle, and listening to nursery rhymes on it.
This time he shows his anger a lot. He says "I love you" if we support him and says "I hate you" if we don't.
We play make believe play a lot with him. He likes to act like a Little mouse very much.
He still is a messy eater.
