Laura, you and Stefan are GREAT parents! Anyone will be able to see that; please don't worry.
Our second homestudy was done by the same social woker that was doing Carolina's post-placement visits, so she already knew us and I wasn't nervous, but I can imagine you are a little stressed. Another poster mentioned safety stuff - some SWs look for that and some don't (ours didn't) so go through the house and make sure there are no obvious hazards; Sabrina is already 2 1/2, so you probably don't have gates up or anything like that, which they wouldn't expect.
And then when she leaves have a glass of wine
BTW, we all wing it. I may start out the day with an agenda, but try explaining that to my kids
