A.L.
Are you positive that she doesn't have an ear infection? My older son has never had one, but the only way we could tell that our younger son had one is when we put him to bed he would cry. Our pediatrician told us that when you lie a child with an ear infection flat, it increases the pressure in his or her ears, which is painful and why they cry after being put to bed. When your raise her head back up again (ie when you are holding her), it decreases the pressure, which allows her to sleep again comfortably. Maybe this is why she cries every time you lie her back down again? I'm sure you're pretty familiar with her symptoms that are specific to an ear infection being that she's had them quite often, but I just thought I would pass on what happened to us. Hope it helps!
