Yup. We have seen the tendency absolutely consistently across developmental areas. I actually was stressed about it the first few times we saw it, becuase of the long periods of 0 progress.
Since I wrote the last post, he has met and exceeded the 50-word 20mo low-avg cut-off, a growth rate in excess of the standard "smooth progression" estimates, and had a very dramatic increase in number of attempts to speak a familliar word/hr. That HAD to happen before a vocabulary explosion could reach the 200 word-at-24-mos cut off the SLP said she'd look for (her paper suggests a 70 word cut-off). So evidence is increasing for an explosion event circa 20 mos (rounding from the .5s, right
. I've got my fingers crossed that we see a big explosion that has us well over the 24 mo cut offs, but at this point, we've made the 20 mo numbers and he's technically "normal"
If he progresses normally, he'll be normal at 24 mos. (if he stalls and starts again, he may still miss the cut-off)
I am not discounting the appt itself as the trigger for this explosion, just for the record
(Though it *did* appear to start three days before the appt -- maybe he was reacting to us talking about speech a bunch)
