Hi

I have a four month old daughter who used to sleep for 5-6 hrs until recently. Now she wakes up atleast 3 times during night and won't go back to sleep until she is fed. She does not seem to be hungry but wants to suck all the time.We are trying Sear's method for the past couple of nights without success and don't want to try "cry it out" way yet.Any suggestions?Is it common to see this change at this age and how long does it last?
