Do you mean pregnancy items for you?
I really like Mama Mio tummy rub and lucky legs
Body pillow or pregnancy pillow
Wide shoes (not everyone will need this but my feet swelled a lot my last few weeks)
Dye and perfume free detergent to wash everything (including your clothes and sheets)
Comfortable maternity clothes
Birth plan (at least an idea of what you want)
Pedi (interview and select before the baby is born)
ETA: and if you plan to BF, I suggest taking a class and having a LC ready to go if you need it.
