My 17 w.o DD has been sleeping through from 10 weeks (and I know we are so lucky). Me and DH are now thinking we'be been TOO lucky up to press and were gonna get it all now because she has now taken to waking several times in a night for no apparent reason. She doesn't always cry, sometimes just chatters. We've tried giving her her dummy and sometimes this will work but other times she just spits it out. She doesn't appear to be too cold/hot or hungry. I'm guessing 4 month regression? Would be interested in hearing your experiences.
