My DD is 3 and 1/2 months and is generally a good sleeper, and was able to resettle herself (sometimes) during her day naps. Now she doesn't re-settle without some help from me. And when I say help, I mean I have to get her out of her cot and give her a bit of a cuddle and rock, and it's off the lullaby land for her .

I know we're not supposed to pick them up to re-settle but I have tried everything, patting, shhhing, no eye contact (hell I even tried eye contact) gentle talking etc. Is there anything I can do to help her to re-settle without picking her up?
