I know this isn't an excuse, but with some organizations or lists caregivers are specifically told that unless we believe we can meet the needs of the daycare parent who is inquiring not to email them back. That the parent doesn't want to be bombarded with emails saying 'Sorry I can't meet your needs'. So, the lack of response might not be that the caregiver doesn't have space, it might be the caregivers can't meet your needs, whether it be hours of operation, age of child, etc.

I can't say 100% that a family gets a response for every inquiry I receive. Truthfully, some slip through the cracks, filtered wrong in my inbox, some seem like junk mail ~ I get at least 2 'fake' inquiries per week, some I mark to respond to later and later doesn't happen, or I am advertising a space for a 1 - 4 yr old and the family is requestion informtion for a 6 yr old etc.
