I have a 20 week old DD. From three to fourteen weeks, she suffered with colic, she also has reflux (and is ff). When the colic was bad ie, she would scream for two hours a night on average, she would go down at aroun d 10pm, wake once, and often lie in until 10am. Fast forward six weeks and she is awful at night. She goes to bed at 8pm or just before usually, sleeps until midnight, although she sometimes stirs before then, and I have to put her dummy back in for her to go back off. After she has fed at midnight (she doesn't always finish the feed) she seems to wake quite a number of times between midnight and 8am.
She actually only feeds twice in the night, but wakes several times on top of this. She sleeps for short spells during the day, but won't fall asleep on her own, she has to be either in her pram or the amby hammock, even then, she usually cries before she goes off. She naps for around 20-30 mins, although she sleeps longer if out in the pram, or car. I know there isn't a magic cure, just hoping for a bit of advice/reassurance that it will get better.
