Does she arch at all? How long does it take for you to calm her/her to go back to sleep at night?? Has she tried a new food recently? 9 months is a regression- but ds2 had food allergies that became quite clear at this point. He only wanted to nurse but sometimes that wouldn't even cut it (If I had eaten an unknown allergen) he'd arch & pull his legs up & yell... & only slept 20 mins of every hour.
