T.K.
if she wakes up screaming when you lay her down even if she is sleeping and is still sleeping when you lay her down i would say she is probably still experiencing some pain maybe sinus or inner ear. i would take her to her dr and tell him what is happening and i would keep her head up for a while. If he cant see anything ask to take her to an ear nose adn throat specialist.
to keep head up in a crib you take a pillow and lift the mattress and put the pillow under the mattress at the end then put the mattress back down so the whole crib mattress only is tilted.
good luck
