yep - definately an oestrogen issue - we ar ehaving the same probs and did with Willy. My lovely dr presribed me oestrogen in the form of the gorgeously titled 'vagifem' and i'm sure you can guess where you have to stick it!!!!! I've only been using it a few weeks and have yet to try dtd since starting it but am praying it helps. Apparently it's to do with bf so my dr tells me which makes sense as i was unable to bf my fist and had no probs with him but fed my 2nd and was still having probs 10 months after his birth (c/s too) and now Isla - bf and probs. Not stopping the bf though just using the extra oestrogen.

good luck
