3 year old son diagnosed with cognitive delay. Anyone else have experience with this?

My son has been in early intervention since he was a baby. He wasn't hitting his milestones and I was worried, so when he was about nine months old I had him evaluated with the early intervention program (if you live in the US I can't recommend this program enough. It's through the public school and you can get a free evaluation for your child to find out if they are delayed and then get them services). He was delayed in several areas and they started him on occupational therapy and physical therapy.​He has made a ton of progress these last years , and when they told me they were going to reevaluate him on his third birthday to see if he needed continued services, I pretty much expected that they would say he was all caught up and they were going to discontinue services. Well, nope, that's not what they said. He has a "significant" cognitive delay. His speech is just below average, not delayed, so that's why he seemed fine to me. But his cognitive skills (things like puzzles, matching things in like groups, finding a hidden object) are not where an average three year old's are. In fact, they are more than two standard deviations below where an average three year old's abilities are.​The early intervention team was really reassuring that a delay in a three year old doesn't mean life long cognitive impairment. That with intervention a lot of kids with these sorts of delays catch up to average or close to average. But I'm still left shocked, sad, and worried for his future.​The other kind of sad thing is that he is going to go to a head start preschool where he can get the specific therapies he needs, instead of to the preschool his two older sisters went to. He used to go with me to drop them off every morning, and he started talking about going there himself like a big boy when he was two. He already started at the preschool his sisters went to a few months ago, and he freaking loves it there. He loves the teacher. He runs happily into school every day. I toured the head start preschool that he will be moving to, and my husband and I both agree it's the best thing for him. We talked to the director and his new teacher, and his new school has such a better understanding of his delay and how to help him. I know he will adjust to the switch in schools. But it still breaks my heart. I was so excited for him to go through that same preschool and participate in all the traditions there that his sisters did.​Has anyone else gotten a diagnosis of cognitive delay for a preschooler? I'd so appreciate your experience, advice, or thoughts. Thank you! via /r/Parenting https://ift.tt/2XZ4Pk8
