The 30-year-old actress opened up on the infant in an interview with Today on Thursday. Wilde and fiancé Jason Sudeikis welcomed Otis in April 2014, and the star said the 10-month-old is growing and learning quickly.
"He's about to walk," she shared. "He's teetering and I just don't want him to do it while I'm at work. He's so smart and just plays his piano all day long. He's really musical so we're trying to encourage that."
