It would be better if you posted the names of the cities you were going to and not the countries. It would be like me telling you I want to go to California, Oregon, Colorado, Nevada, Arizona and Washington and spending 1 maybe 2 days in each state. You would have no idea where I was going L.A. or San Francisco, Reno or Las Vegas, and so you could not answer the questions - Will this be too much of a trip? Will this cost a lot? Answer - Yes & Yes.
You are jumping all over the continent and it doesn't make much sense. If you are in Munich, why would you first go to Berlin then London for a day, then to Paris, then down to Switzerland, then to Italy and then to Austria? You have left no time for travel. You do not get to another country in an hours time unless you are staying in the Benelux area. If I understand you right, you fly on the 29th which means you land on the 30th. This gives you 11 days to go to 6 countries, with a child dragging behind you. This truly does not sound like a fun trip at all for anyone. Please read some of the other posts on here to get a bit more of an idea of what I am talking about. Especially if you are on a budget! If you fly, it is usually more expensive. If you take a train, say from Munich to Berlin, this is close to 7 hours. London to Paris on the train is 6 hours. If you fly, you have to figure in your travel time to the airport, check-in times, flight, and getting to the city center of your next stop. Airports are usually far out and the trains cost money coming into the city. Train stations are usually in the city centers.
So, get your map out, plug in some travel times, read some more of this website and then come back.
