Oliver still doesn't speak a word, but he knows what a rooster and a lion say. Sometimes when asked what they say he'll make the sound all on his own and sometimes we have to make the sound first then he'll do it. It's pretty amazing! He will do it consistently too. Well, at least the rooster sound, which is more of a screach/squeal for him. The tiger is brand new so we don't know how consistent that sound is yet.
The occupational therapist came today and got us started on a brushing technique to hopefully better regulate him and keep him from banging his head when he's upset. So far he's pretty fidgety and doesn't like to sit there the whole time, but we've only done it twice. We also do a joint compression method along with the brush method. It will take time to see if they benefit him.
UPDATE!!
About 30 seconds after posting the above message Oliver wanted to go outside. He usually goes over to the door and knocks, reaches for the doorknob, or bangs his head on it. We always encourage him to go get his shoes so he can go outside. This time without any cue from us he knocked on the door and then went and grabbed his shoes and brought them to me (Dad) so I could put them on him. AMAZING!!
