Gadgets or clothing that can make life of postpartum mom easier

My bestie is giving birth to her 2nd child soon, what gadgets/things changed your life and made it easier during your recovery?

Diapers, new bottles are already on the list.

I did a previous search and people mentioned food but I live in another state, another popular mention was shampoo/hand cream but my friend has very very sensitive skin so she sticks to what she knows.
