Why did Lewis and Clark believe that the presence of Sacagawea's baby might have a beneficial effect on the expedition?

Answer 1

Because ultimately, if they were ever stopped or taken by tribes along their journey, having a baby would show they had peaceful intent and were not a hostile war party, as it was known that indian war parties did not travel with women and children in their group.

Answer 2

After the expedition, William Clark offered Toussaint and Sacajawea a place in St. Louis and a proper education for Jean-Baptiste (at a time where there was no opportunity for Native Americans to receive an education). Toussaint then took a job with the Missouri Fur Company, and stayed at Fort Manuel Lisa in present-day North Dakota. Evidence suggests that Sacagawea died at the fort in 1812. After her death, Toussaint signed over complete custody of his son Jean-Baptiste and his daughter Lisette over to William Clark.
