Your soon looks vert cute. I Wish good give him good health. I too have my sister son. I know what kind of stage you are passing through. Parents always overwhelm when their child do grow by performing new task. You will very good when he walk to you with his legs. Just take care of him. I am sharing you my sister son "Vihaan" i love him very much. 
You while feel very good when he stand himself and start walking. That time it is hard for you to stop him like my nephew. He is very naughty now.
Thanks for the great comment. I am very pleased to read such informative comments. Good luck to you and and kind regards
