Alyson Hannigan and her daughter's

The 'How I Met Your Mother' star's 18-month-old, Keeva Jane, is already turning into a domestic goddess and keen to help with household chores, despite her young age.

Alyson told People magazine: "She's sort of a perfectionist. The other day, we were going outside after a snack, and I said, 'Where's Keeva?'

"I went back and she was taking her plate from her little table and trying to put it on the counter, which she couldn't reach.

"I was like, 'She's putting the dishes away!' She [made] me look really bad so then I went and did it too - I had to."

Alyson - who also has four-year-old daughter Satyana Marie with husband Alexis Denisof - has also been making festive decorations with her young ones, in preparation for Santa's arrival in two weeks time.

She added: "My husband [Alexis Denisof] said we should try doing some more homemade decorations this year, so we've been doing that as a family.

"I made a bunch of pom-poms and draped them from a ribbon. Then you tape them onto the ceiling. The kids love it because they try to jump and hit them. It's a lot of bang for a little buck."
