A breakthrough?

My sensory boy has been in speech therapy for about five months and it's been four months since his diagnosis. He has come so far from throwing himself face down onto the ground with no regard for safety because he was frustrated. This week has been a week of small miracles, in my book. We spent the weekend with my brothers and one of them said, "I never heard his voice before. He wasn't even making sounds the last time I saw him!" My brother has no children and doesn't quite understand Sensory Processing Disorder but the fact that he noticed a change was huge. We have heard many new unsolicited words this week including milk (mi mi mi), juice (ju), apple (which was very clearly apple), and thank you (na new.) A huge breakthrough has been the fact that he is saying people's names. He has attempted his brother's name, both of his uncle's names, and one of his friend's names. It's been a really good week and I have so much hope that SPD won't be a hindrance to his life, just a minor obstacle to tackle.
