Hi all - I have an 11 month old daughter who has never been a very good sleeper. For the first 4 or 5 months she would sleep 3 hour stretches. Since 6 months old, it has been 1-2 hours, and lately every 45 minutes. However for the past 4 or 5 months she frequently wakes up screaming. I try to nurse her (which is usually all she needs) or I pick her up, but she continues to arch her back and cry. Sometimes we have to turn on the lights for her to calm down. We have co-slept since birth and she is still nursing. CIO is not an option for us. I can handle the waking, it's the screaming that is bothering me. Doctors suspected she had GERD when she was younger, so I'm wondering if that could be the problem, or possibly an allergy or sensitivity to something I'm consuming (she doesn't eat a lot of solids, and this started pre-solids). Any insight would be great. Thanks in advance!
