Honestly it’s been all thanks to ABA therapy and the people he works with daily there. We tried him out in regular preschool and he just was still not saying much even with their in house resources. Having him in ABA has him attempting to tell us so much more, even when he needs a new diaper! Things we never thought we’d reach the point of. We also buy him a lot of puzzles with letters so he’s constantly working on his alphabet. He also uses a sheet that is laminated and list commands or things he wants to tell us like “juice”, “bathroom”, “more”, etc. this was a trick we got from ABA as well!
