My son is 3 years and 2 months and has been undergoing an ABA programme since September last year. He is still non verbal, but his concentration has improved dramatically as have his social skills. His ABA tutor attends his nursery 4 days a week and he has 2 hours at home on the day he isn't at nursery. The new ABA approach certainly isn't "Pavlov dog" training. My son's programme is learning through play.It is expensive, but for us, has definitely been worth it. We also found out through ABA that our son knew a lot more than we anticipated (the alphabet, colours etc) It is tough, as it is hard to know what to do for the best. Have you attended any of the early years courses offered by Southwark?
