Sounds like a normal 3 month old to me. They go through the fussy phases. Try and keep a calm, consistent routine. You take breaks when you need it also.

There is an Infant Board that you'll find lots of good stuff on. Click on the "Healthboards" and all the different categories will appear, then go to the Infant - 18 mos and under. I think it would benefit you more than this thread.

Hang in there, it does get much better.
