@Bd610,
The support is for the benefit of the child. As long as the child is well cared for and she has documented the money is being used to provide for the child, it is not the business of anyone else what she does with her own money or how often she does it.
Same goes if the roles are reversed. If the father is providing adequate financial support for the child, it is not the business of anyone else what he does with his own money or how often he does it.
Child support is about the child, not the adults.
