Larson acknowledges that she's sharing co-parenting responsibilities with her nanny. Larson's husband, Chris, joked with the nanny when she was interviewed for the job that if she was hired, she was hired for the next 18 years. Larson says that's because her husband also prefers a nanny to look after their kids because both parents are very busy professionals with demanding work and travel schedules.
But do their kids ever get confused as to who's in charge? Larson says her agreement with Sumption is that during the day between 7 a.m. and 5:30 p.m., Sumption is in charge.
She tells her kids to go to Sumption for every want and need during the day. Even at times when Larson is home for a few minutes to grab coffee or lunch, she says "Go to Tia" if her kids ask her what they should eat or wear.
Sumption, on the other hand, observes that 3-year-old Ella often throws temper tantrums while both Larson and nanny are in the house during the day.
"She'd wonder mom's here, but Tia is not gone, who's the boss now?" said Sumption.
Larson agrees that when she works from her home office, it can be confusing for her kids. She sometimes worries her nanny may have an impact on her children's long-term development. But child psychologists say while children may cling and listen to their nannies more often than their mothers during the day, it's the mother who will, over time, have a bigger influence on the children.
When Ella was asked what kind of mom she wants to be when she grows up, she's confused saying "stay at home" and "go to work!"
