I can't believe how soon your little man is going to be making his appearance! How are you feeling? Can you fit one of DF's jackets? I know I wore DH's sweatshirt hoody on chilly days. It wasn't really a fashion statement, but I hated to buy a maternity jacket for just the few chilly days in Sept.
The rest of your month sounds incredibly fun. Lilyana is going to have a blast at Boo at the Zoo / trick or treating and Kalahari. It sounds like you have lots of good times planned to finish off her last month as an only :)
