Welcome to Lugano! Have you looked into the American Women of Ticino (www.awot.ch
) or the International Women's Club of Lugano (www.iwcl.org)?
Both organizations have activities for kids. These may be a good start! I also have a daughter who is 5 and a son who is 8. They were 3 and 6 when we arrived.
Both speak English and Italian. We arrived here 1-1/2 years ago. Neither spoke any Italian when we arrived. They speak very well now! Your daughter will pick up the language in no time.
