Babysitting movie

Babysitting movie (i think) and siblings (a blonde younger sister and the brother is slightly older with brown hair) both quite young. They are on the run around a mall or aquarium with money that their babysitter wants. She sends security on the kids so they are basically on the run around the place they are in. By the end the kids dump the money into the water and it falls in and the babysitter is very upset with them. Could’ve been early 2000’s or older!!

you are sure it was a babysitter? it was guaranteed to be money/cash she was chasing them for? it was in english? do you have any more specifics? could it be newer than say 2009?
