Malin Akerman's son can speak three languages.

She told PEOPLE.com: "I feel like every day is a milestone, but he's running and walking up and down steps on his own now talking three languages, so it's amazing. Whenever he sees his dad he starts speaking Italian, he sees me and starts speaking Swedish, and his nanny speaks English. So, it's really just amazing to watch how a child's brain works."

The 'Couples Retreat' star has even been teaching the little one how to be eco-friendly.

She explained: "I have solar panels, I have a hybrid car. We turn off light switches, which is very exciting for Sebastian because he loves turning off and on lights, so he helps me turn off the light switches when we leave a room. He's just tall enough to reach that."

Meanwhile, Malin admits she loves every bit of motherhood and was surprised by how much love she felt for the toddler as soon as she locked eyes on him.

She said: "I guess the most surprising, although everyone tells you, is the love that you feel for your child. You need nothing else in the world but your child. That's it. He's the air that I breathe."
