I've tried quite a few of sleep bra's and this one by far is a better quality bra, very soft with just a little support.  I have to admit. I do wish there was one like this with a tad more support but this one is essential for those first few weeks of nursing as your body gets used to nursing and you deal with issues like engorgement, sensitive, raw nipples.  Alot of the other bras I have are a bit firmer and more support and therefore more "tug" on the boob.  Not fun for a newly nursing set of boobs.

I highly recommend this and as per a previous reviewer I'd say she got the sizing spot on.  This is definitely a must have for a new nursing mom.  I sleep in it. and for the 1st 3 weeks have basically lived in it....

Update: 7/10/12

I have had 4 pairs of these since I gave birth,and I have to say I am now down to wearing only these all the time.  Yes the boobs droop, but if these were tighter then they are now... with more support... they would not be as gloriously comfortable and perfect for nursing as they are now.  I LOVE these!!!! I'll be buying more of them just to sleep in even after I'm done nursing!
