For bubs, check with hospital what they supply.. We didn't have to take anything, but I felt better dressing mine in our own clothes. They also supplied bottles/formula. So unless you have a particular brand in mind, you may not need anything.

For you.. I enjoyed being in my own clothes, so I took clothes that I wore through the pregnancy so they were still loose, but I was not in pj's through the day (I just needed to get dressed, hospital didn't care).. Also, my eyes dried out with the air con, so some eye drops might be handy..
