As moms all over the world know, sometimes kids can be a little, well, picky.
While talking to Conan O'Brien on his TBS late-night show "Conan," Witherspoon did a hilarious impression of her 2-year-old son Tennessee, who she says only likes three things: white bread, ketchup and milk.
Yes, Reese. We've been there, too.
And despite preparing adorable plates of fun food, which Witherspoon shares on her Instagram feed, her son often refuses to eat it.
"I have no idea how he's alive," she quips about Tennessee, whose dad is talent agent Jim Toth.
Watch as the mother of three (she also has Ava, 15, and Deacon, 11, from her previous marriage to Ryan Phillippe) imitates her young son.
