Coincidence or Correlation?

I'm putting together the paperwork the GI specialist asked me to bring about Baby E. One thing they wanted was detailed records of her height and weight. I wrote up a summary of my records and then charted it.

We introduced solids between 5 and 6 months--starting with rice cereal (which contained corn derivatives) and barley cereal (which contained soy derivatives, unknown to us, and of course contained gluten also). Her growth curve went flat from that point until between 11 and 12 months.

Between 11 and 12 months was when we removed corn and its derivatives from her diet. We didn't see an improvement in her behavior until all corn and soy derivatives were removed--even the most refined "non-allergenic" ones.

I find it very interesting that between 11 and 12 months was when her growth curve started going up again.

It may or may not be causative, but the exact correlation is certainly interesting.
