6 and half months old- night waking every hour, crying

[Berezowsky]

Hi, My baby is 6.5 months old and used to be a fairly good sleeper at night but the past 10 days he has been waking up crying every 45-60 minutes. He does not seem to be teething, sick or hungry. He started solid foods a little over a month ago.

If I am reading this correctly, there is a 4 hour A to bed. Is that right?  The average A is 2.75-3 hours http://babywhispererforums.com/index.php?topic=64158.msg476652#msg476652  that could definitely cause NWs.

I am also wondering about teeth.  Have you tried medicating at bedtime?  Waking up that often signals discomfort to me.

Anything else happening developmentally?
