Translation of baby-sit in German

As I have already mentioned in my last email, it is a breakthrough, I have never been so successful. I have visited several Spanish schools and would like to discuss that by telephone with you.
I really value honest comments, and I am a believer that it is the only way that the social community system works, so as to know whom you can trust on both sides. Programmers did a great job if you were asking me.
If you want we can exchange our phone numbers, then we can communicate better. I can then correct your German pronunciation, and you can do the same for my Spanish. What do you think?
