Approved, but homestudy not done. What do I do?

Hi Everyone, My husband and I are new to all of this. We completed our MAPP training in Massachusetts and had our final Homestudy meeting last Thursday. Our SW said that we were Approved, yeah! However, our homestudy isn't completed yet. We still have to get our physicals although there won't be any problem with that. My question is, when do we start getting calls about potential children? We are looking to adopt 1 child. We saw a child that we are interested in, should I call our SW now? This is all so new to us. Our SW is a complete sweetheart, we really like her. But, how hard do they work for you? Any help would be appreciated! We are so ready to be a Mommy & Daddy! Thanks!
