washable, re-usable lush breastpads
several WAHM brands are available at the clothpadshop site, and there is also Mazalicious brand.
Swaddlebees is one commercial brand i can think of.
great for saving the new mum from having embarrassing wet patches on her front, when her milk comes in.
the bps are funky, and the soft layers against the skin feel so nice, like TLC for the mum.

lingerie washbags to wash the bps in, keep them together, so you don't lose the pairs in the washload.

aba calendar
aba subs (so the new mum will get the bi-monthly magazine ESSENCE delivered to her letterbox)
i could add breastfeeding tops (from places like nuvo maternity)

i think the BEST gift, in the few months, would be a friend to talk to about nb stuff - she obviously already has a wonderful friendship with you, so i think she's a winner before you buy ANYTHING for this New Mum Basket.
