some ppl like to have a camera with them; other than that I think everything else has been mentioned! Def take the teddy, it could be quite comforting. Oh- and if something happens and you need a c-section or if you go in before the baby is born (e.g. from the high blood pressure) I found it nice being able to wear some comfy clothes from home while in hospital rather than their gowns (esp for when visitors came, and my own self esteem). Most ppl don't cover these 'scenarios' but I was in for 4 weeks before I had my 1st...
Best of luck.
