Hi I'm Sara! I need help to learn better English ! I am going to London in June and I will be a baby sitter in an English family! I understand English a bit but I can't speak at all.

I expect that you will pick it up when you are here.  If you are staying with an English family, they will talk to you in English.  You can also meet English-speaking people around the city.
