Don't know if it differs between states but there was one medical form which the doctor did (you can print that part out if you need that filled out (e.g. have an appointment)before the claim form reaches you), and the claim form, which they sent when I called to request the form, they ask questions to pre fill some details, and you have about 14 days to get it back. Though I took longer with the medical part and that was fine. The claim form didn't seem to require too much filling in (as in, I don't remember crying or kicking anything while completing it), so I don't think it asked how it impacted me, apart from an obligatory 'do you work extra hard with this kid, and if you don't, you might not be eligible'.

So I think you will want a professional on side. I'm pretty sure I saw psychologist on the list of people who can fill out the med form?
Here ya go, it says a registered psych is fine. All the best, every little bit helps hey.
