I am just about to submit my phd (is there a party smiley face?). Writing the acknowledgements eloquently is more difficult that the actual work though
My superviser suggested I do a dedication to my DC's. I had them both during the course of the PhD and they have been very insipirational (its about breastfeeding).
What did you put? Did you put anything? After some ideas. In terms of acknowledgements I have worked through thanking family etc, those who have helped me academically, the mums who filled in my questionnaires and did interviews and so on.
Just being nosey
