I'm sure this sort of thing has been posted loads on this site but just need a little reassurance / advice!!
My 16 week old DD is getting increasingly hard to settle to sleep at night. Since christmas we take her upstairs about 9am, I feed her in the bedroom in dim light and then my dh walks her until she gets drowsy and is falling asleep and then he pops her into the moses basket and she sleeps through to between 8 and 9am the next morning. However over the last few weeks every time we put her down to sleep, she immediately wakes herself up crying- this happens again and again and over the last few nights we have not been able to get her to sleep until about 1am. She is exhausted at this point with all the usual sleep signs and is over tired too which doesn't help.....
BTW, she naps during the days every 3 hours or so for about 20mins to half an hour.Her last nap is at about 7 or 8pm in the evening.
Why does she wake herself up again so easily? is this this 4 month sleep regression thing or are we doing something wrong? please help..... as its getting soo frustrating!!!!
