She's one busy mom on the go.
After a busy Fourth of July holiday that included ice cream and an at-home celebration
with her family, Katie Holmes
took daughter Suri to the Children's Museum of the Arts
in New York on Thursday.
The mother-daughter duo, who moved into a new, three-bedroom home
, were matching in pink patterns as they arrived with bodyguards to face waiting photographers.
Later in the day the 6-year-old played "doorman" at Alice's Teacup on New York's Upper East Side. "Suri walked out with a shopping bag and a sparkly fairy wand," an onlooker tells PEOPLE. "She
insisted on holding the door for the whole group. Very sweet – so polite."
Holmes, 33, filed for divorce from Tom Cruise
last week in a decision sources say blindsided the actor
, who spent his 50th birthday
at home in Los Angeles with his older children, Connor, 17, and Isabella, 19.
