What a lot of people do not realize is that while the main petition is pending, you may request temporary orders
that will spell out custody and child support
until the Court touches base again at the hearing on the merits (i.e. trial).
So you could have done this. If you have not, then both parents have natural rights to the children and to take and keep them away. Both you and she can (peacefully) take the child whenever you want, and of course this gray area creates a lot of frustration for parents who cannot get along (hence, the availability of the temporary orders).
So yes, she can do this since no order is in place and in order to get access to the children, you may want to consider filing for temporary
orders that would be heard 2-4 weeks after filing.
