That said, I don't think a week is that long of a response time if you have to coordinate other people's schedules. My in-laws do this to us, they want to book times to visit and don't seem to comprehend that we have other commitments to juggle and we don't always know the exact dates. So they start pushing us for weekends that are good for us and get frustrated when we can't answer them immediately.
Your MiL may be waiting to hear what the step-kids schedules are (especially if there is a shared custody situation) before she can let you know what works.
