The first thing on Nicole Richie's plate after welcoming newborn son Sparrow?

"Next Stop: SUSHI" the mom, 27, posted on Twitter early Friday morning.

When pregnant women eat sushi, they ingest bacteria that could make them sick and even miscarriage.

This isn't Richie's first Twitter post about Sparrow James Midnight Madden -- who weighed 7 lbs. 14 oz., and was born early Wednesday morning. (He joins older sister Harlow Winter Kate Madden, who was born in January 2008.)

On Thursday, Richie  posted: "What a great day to come back on. Thank you everyone for your well wishes. I love my family!!"

Added Madden, 30: "1st day of his life & my son is already a trending topic on twitter. That's right son, ur just like your old man."
