Little man had reflux issues so doc put him on meds when he was about 6 weeks. in until Friday night he has pretty much slept through the night. He got his shots for 4 months Friday so I am not sure if this has anything to do with it but now he is waking up every two hours. I think he is teething although nothing has popped through. he is drooling uncontrollably and shoving anything he can in his mouth.
