Hi, I'm travelling end of Oct to Beijing without tour package. I have a 2 year old son. what kind of clothes should I prepare for my son? should i bring scaf, gloves and thermal wear?

I will reach Beijing airport 7am and need to travel to hotel near Tiananmen square. Will there be morning traffic jam and should i wait till off peak hours in airport to take a cab?

It is better to buy individual tour package like great wall, summer palace from beijing hotels or just take a cab and go there to buy tickets?
