When my 1mo old gets in pain around feedings, he arches so bad that he stand up in our lap. he goes stiff, neck elongated and legs straightened and stiffed. I’m not sure what his eyes are doing at the time. I will pay more attention. THe “fussy” period coudl last minutes to hours but the actual posturing lasts seconds, then he relaxes and it may start again. How do you tell the difference b/t regular arching with GERD and sandifer’s. Is sandifer’s where they stiffen and stay stiffened/arched for a longer period of time? Thanks! I watched the video on marci-kids showing a sandifers reaction and i know it’s only an animation but it’s exactly what DS#2 does. Kim
