Leap 3??

During leaps 1 and 2 my daughter didn't get much fussier than usual and her sleep didn't seem too affected (not like she was sleeping super awesome anyway but it was still all night with a few wakings to eat and right back to sleep). This time however she has been almost impossible at night. Completely hysterical with nothing working. Usually I can swaddle her and rock her for a minute, put her down awake, and she'll fall asleep on her own. She even slept for six hours straight two days in a row a few days ago and I thought we were making progress. Is anyone else experiencing this??
