By 9 months

There have been 9 months of an unbelievable development. Even if people are telling you that "babies are growing fast", "enjoy these moments when they are babies", you just kinda live in the moment and don't understand what they are saying.
And then there are moments when you wake up in the morning and you ask yourself: "Where is my little baby?"
After only 9 months of unbelievable development, I need to write down some of the skills that he masters as of this age:

- sits perfectly;
- crawls very, very fast;
- pull himself to a stand with no problem;
- cruises from point A to point B;
- exquisite pincer grip;
- understands "no" but doesn't always obey it;
- says "baba";
- says "aaa" when he wants something;
- drinks from a sippy cup;
- waves "bye-bye" but not necessarily  when somebody is leaving or waving to him;
- very sociable;
- smiles, returns smiles and interacts with people who are interacting with him;
- loves to bang on any firm surface;
- very, very interested in music;
- plays peek-a-boo;
- throws the food on the floor when he's done eating;
- has only one tooth;
