you are welcome sally. Oh and I also found this woman 'Risca Soloman' who is trained in talk tools. Talk tools are mainly used for speech production etc but we went to see her for ds1's feeding issues as she uses talk tools with ABA and it was worth every penny. She is on here as well under the name of pleasant spice if you are interested in that at all.
Thanks, what a great website. The section about the AAC apps is very interesting. Ds is going to have a meeting with a SALT who wants to go through The Grid and Grid Player apps, with him, so I will have a proper read through later.
