I've read the thread, at last.
Brangelina, welcome back! So good to see you dear, how are things?
Eurocommuter, how bizarre, I've always found that Italians are generally rather enthusiastic of bilingual children, especially if the second language is English! Ds's teacher for instance is always keen to have him as a helper during the ora di inglese at school.
Are there many foreign children in your ds's school? Perhaps they aren't enough for the language course and are looking to fill it?
Gio, yes, I'm now worrying that the presence of a zarahome that I can reach in less than 15 minutes tram ride will seriously endanger my credit card.
Sorry to hear about ds, sadly, it is something that can occurr at asilo, especially with the younger ones, who are still a bit "selvaggi" 
SG: I've never felt like an expat (I loathe the term), but I've always felt I didn't belong 100%, even if it really got better once I made some (a handful) real friends and I witnessed the children being so at ease at nursery, school, at the gym club etc.
I think that in general it is difficult being a new mother when you are far from your friends and family. New mothers, I believe, need sympathetic ears and some practical help, that's my mantra.
