my baby is 20 months old and since yesterday after her nap, she is dull , drowsy looking , and cranky , she just wants to be on my arm and only in one position , she is not crying all the time not happy or active at all. She slept for 12 hours and got up and throw up and went back to sleep for another 1 1/2 . Not sure what is going on with her . no fever but a runny nose and congested chest for 5 weeks
