yes, I have been there. My LO was sleeping through the night and and then suddenly started waking up 5-6 times a night with one major outburst that required rocking for over 10 minutes. He has reflux and is on medication that really seems to help. He moves a lot at night and is of course teething. Per my pediatrician it is a combo of new milestones, teething and reflux. He suggested tylenol at bed time for about a week to see if it helped with his teething. Now we only give it as needed. It has gotten much better and now wakes up maybe once a night. Hang in there and Good luck!View Thread
