Lol, me too zzzzz!
Aika, I have "been in the system" a looong time, & a bit (a lot) of a cynic.
But, if this request has made you uncomfortable, I would trust your gut instinct. If someone wants to do a home visit, they should be able to look you in the eye & give clear, concise reasons for doing so. If she can't do this, say no.
You will learn, as you go through the system with your ds, that some professionals have another agenda, other than what they say to your face. Like in other professions, you will find good & "bad" people. You will also find, that profess. talk with each other freely. Anytime a profess. says they are going to write a Report on your ds, ask for a copy, & keep a note of e-mails & telephone calls.
Sorry, but I did laugh, when you said to a previous poster, "why would they say that about your house, would they help you get another one?" You would think, wouldn't you? But, for some reason, when you have a dc with SN, some profess. think they can say what they want, however unjustified, however pointless, then walk out of your life, leaving you upset & questioning yourself.
I don't want to put you off seeking help for your ds, but always trust your instinct, & develop some broad shoulders! x
