My LO is 10 weeks and in the last week, she has been arching her back more after eating (she kind of twists her head to the side and arches) and throwing herself backwards. There has been a few times where she was just screaming and I don't know why - maybe once a day for a few days in a row. She doesn't spit up much, so I'm wondering if it is silent reflux. It seems like it should have started earlier than 10 weeks, though, right? Maybe she is just being fussy? When did your LO's reflux start? She has started drooling a bit more recently...and she has always swallowed randomly during the day (not while eating)...are those symptoms too?
