Brief background: DD1 is 3 years and 8 months. No formal diagnosis but lots of warning signs for autism (developmentally delayed in all areas, unable to independently speak sentences for example, but will 'parrot' lots of things she has head from us / TV; doesn't interact with other children, makes a 'humming' noise a lots, very distressed by changes to routine etc). We're awaiting a lot of appointments right now including SALT but there seem to be long waits for everything, and we have no formal support in place for her right now.
Her nursery referred her to the Early Years intervention service (the local council education support service for pre-schoolers) and we had a letter through last week to say her referral had been accepted, and she would be assessed in a couple of weeks time (they are coming to see her at nursery and at home). What are they likely to offer us in terms of support? I'm new to all of this and I'm not really sure what help we should be expecting and what the process is.
