When Alyson Hannigan needs some "me time" away from baby daughter Keeva, 8 months, the actress can rely on older child Satyana to occupy her youngest during playtime. "Satyana is just thriving, she loves it so much and never once has exhibited any sort of sibling rivalry or jealousy. She just adores her little sister," the busy mom of two, 38, tells Us Weekly.
Satyana, who celebrates her fourth birthday March 24, isn't just handy when it comes to keeping Keeva occupied with make-believe: She's a wonderful mommy's helper, too. "Any time Keeva fusses Sati will start humming her a lullaby and it totally works!" beams Hannigan, who also shares a birthday with Satyana. "I'll just mention, 'Oh, I'm going to go change her diaper,' and . . . Sati's there with the diaper already ready to help."
"It melts your heart, the love that they have for each other and I can't believe that at this age you can already see the sisterly bond," continues the actress, who married her Buffy the Vampire Slayer costar Alexis Denisof in 2003.
One other thing Satyana's especially good at? Saving mom Hannigan money at the mall! "When she outgrows something she'll be like, 'Oh I'll go put this in Keeva's room!'" says the star of her budding fashionista, whom mom allows to completely dress herself. (Among her favorite fashion choices: Pink fringe boots and anything with polka dots.)
