OT: My 22 month old has turned into a whining, crying baby

Our DS started entering the "terrible 2's" at about 21 months. We made a few adjustments that I think helped. I realized that he was whining and having a fit everytime he needed help with something, so I taught him the word 'help', so now i hear 'elp, elp, elp' which is a much more plesant sound than whining. We also realized that he was understanding more than he was communicating, so we started telling him what was going to happen ahead of time, and it seemed to help a bit... i.e. mommy is getting dinner, and it will be ready soon. The other thing we did was to start giving him decisions to make for himself, such as 2 choices for dinner, or two choices of pajamas to change into. We also noticed that he is a very high energy little boy, who gets fussy if he does not get enough exercise, so we try to put LOTS of exercise in his routine. Those things helped us a bit, but I would not say that we have everything figured out yet. Good luck
