It's all so up and down, saw SALT today to get push button communication equipment for DD and she was amazed by how many more words DD had, and even said that she will see her more often soon once there is more to work with, which I think is a great sign as DD was barely getting any SALT as she had no words and not much interaction.
DD used to just ignore the SALT and today ran and gave her a big hug goodbye.
So, hopeful whatever she has is indeed not progressing in wrong direction!
