The actress tells PEOPLE about how her 19-month-old son Otis "is becoming a little individual"

For Olivia Wilde, motherhood is all about watching her son blossom into a “wonderful little person.”

“He is becoming a little individual and his personality is starting to emerge and it’s amazing,” Wilde, 31, tells PEOPLE exclusively about her 19-month-old son, Otis Alexander, during Gap and Bombas‘ — a philanthropic sock company, who currently has an exclusive line available at Gap — in-person sock donation at the Los Angeles Mission, where the partnership will give away one million pairs of warm antimicrobial socks to those in need during this chilly winter season.

“I’m more and more excited to be a mother — and to be his mother — because I think he’s a wonderful little person,” Wilde adds about her firstborn child with Jason Sudeikis, 40.

With the holiday season in full swing, Wilde is busy teaching Otis the value of appreciation.

“I hope that my son ends up equating the holidays with the need to give back more than any other time of the year,” says Wilde. “I think it should be a time when we realize how lucky we are and keep in mind that there are many people who aren’t going to be celebrating the holidays.”

And the actress’ devotion towards helping the less fortunate seems to be a passion that has been engraved in her being since day one.

“This is the kind of project that I look forward to bringing him to once he’s conscious of what it means because I think it’ll be very important for him to have experience with this stuff like I did,” Wilde recalls.

She adds, “I used to go with my mom to give out meals with Meals on Wheels in [Washington], D.C., and those are some of my fondest memories bonding with my mom as a kid, so it’s something that I look forward to doing with him.”
