I have a 3 month old baby.. when she wake up or go in to sleep she will cry (more to like screaming ) anyone encounter this?

Yes, I had similar experience. Baby cry most of the time especially sleeping time. This is due to colic. Baby stomach is not feeling well due to wind. You can try "bicycle kick" motion to relieve the pain. See your paed and confirm whether it is colic. Normally will prescribe colic drop to relieve the pain and reduce wind.
