J.P.
Next time you ask for a playdate, say, where should we have it? Maybe they aren't comfortable having it at their house, or there are other kids, and just too much chaos. A park might be a good location? For me, my son's friend is in a huge, lovely house with a great big backyard. We are in a smaller house with baby stuff all over. It took me awhile to get over myself and just invite them over.
