We show the snack PECS symbol and play the "I like food song" to signal that it is time for our snack. The children are using differentiated PECS symbols (in size, some use photo PECS and a blank, some use up to 10 symbols) to communicate what they would like to eat for snack. Some children using switch devices for their communication. I will email you what stage your child is working at and send the relevant resources in your sensory pack. Please let me know, if you need any further help or support.
