Our son has started to stand and walk

Our son is at 10th month. He has started to stand with support. He can stand if we hold his hands or he holds onto the furniture. Together with crawling he has started to walk on his limbs. Now a days he can sit comfortable and poo on his pot comfortably.
He has learnt some symbols and its meaning behind it, like when we say "bye, bye" he waves his hand, when we say "All is well" he pats his hands on his chest. Similarly he can say "NO" and shakes his head from side to side. He knows our approval or disapproval for his acts. Like when we shout or scold him, he just cries and when we appreciate him, he enjoys and shows his smile at us and hugs us. He also shows his jealousy when we hold other kids. He seems very much moody and upsets easily when we act he doesn't want.
This month, we tried to let him scribble, but he enjoys playing with crayons rather than scribbling.
