Translation of infantile in Spanish

For example, if I am working very early in the morning, let's say 06.00 (that would be 09.00 your time), I don't notice it much. But 9 hours later, the system slows down, because people in Europe get online.
I'm quite tired too by now. So, if it doesn't work just drop me an email and I'll see it first thing in the morning. I wanted to add new words to the dictionary however the other issues kept me more busy than I have imagined.
What do you think of the current situation? Like you, I am writing letters, emails and other messages. Tomorrow I will leave, then I will go to my friend in Spain, where we are planing a beach vacation.
