Because suspension is ready dissolved it tends to act much more quickly when it hits the gut and to some extent is absorbed much faster and before it gets to the small intestine I would have thought.  tablets take a little longer even when crushed.  Are you dissolving them in lukewarm water?  I got around the absorption issue by dissolving them first and squriting them in with a dropper from a little med vial as in effect it was just like giving suspension doing it that way.  

As I said ealier, when children are overtreated, it takes sometime to show up--several months of monitoring before they actually see that and sometimes even a bone x-ray before anything is finally done.  However, when slightly undertreated, it can be picked up right away, as a lack of cortisol usually throws everything out and once higher levels of dheas and androgens start to be made, the pituitary sense that and the lack of cortisol and starts to pump out higher volumes of ACTH.  So it can take only  matter of weeks for that undertreatment to become apparent.  Good that they are keeping a good eye on her as they are.  It’s difficult to say wether they raised too much as your now at the flipside all over again and looking at monitoring for a few times to check if growth is occuring normally in the way of height and weight gains.
