Hi, have you read about Kangaroo care (skin to skin)? There is lots of research demonstating the positive effect of kangaroo care on both babies and parents and it was greatly encouraged in the unit where my DD2 was born at 23+5. I too have read very little relating to attachment disorders and premature birth (never really mentioned in the many books I have here!), however I did talk at length to my daughter's consultant about this while she was in NICU. His view was that attachment takes place over a much longer period than the length of time a premature baby is typically in hospital and that provided we had plenty of opportunities to cuddle and communicate with our baby during her stay in hospital, then it was not something we should be especially concerned about. Naturally I was though!
My experience of kangaroo care was that staff would get DD2 out of the incubator and literally pop her down my top so that she would lie upright on my chest and we would stay like that for hours....and hours! Lovely, lovely bonding time. It was a bit stressful at first as she was very tiny, still ventilated with lots of lines, so I hardly dared move. Also at first it was too much stimulation for her to be out of the incubator, so she could only manage a short "cuddle", but by the time she was 33 weeks, it just became a lovely time, just the two of us. It is a horrifying experience to be away from your baby and to feel that physical separation when they are in the incubator but I can honestly say that looking back at the four months we spent in NICU, my strongest memories are of those precious hours spent snuggling, singing, reading and sleeping with my DD2 during kangaroo time. My husband would also go to the hospital after work (luckily he was working right next door) and have his own kangaroo time in the evenings.
Incidentally there have been no signs so far (and she is 20 months corrected) that the separation she experienced has affected my daughter at all, she has been no different in terms of bonding/attachment/general behaviour from DD1 who had a "perfect" home birth at term.
Hope all goes well xxx
