You don't say what you said in your ad. I know it does not excuse rudeness and it only takes a few seconds for a caregiver to respond saying sorry I have no openings. From talking to other providers a couple things that might be coming into play. If you are looking for more than 3 months away and a caregiver has a space they are really hoping for someone that wants it now rather than having no income for 3 months. Also if you are looking for part time hours or an early drop off or late pick up that can also cause caregivers to hold out a bit longer before replying to you in the sense they don't want to say they don't have a space if it turns out there are no other enquiries with better working hours and they want to contact you afterall. It is also school break in some parts of the country so bear in mind that filling a space down the road isn't the most important thing on the mind of families planning a vacation for the break. Sorry that your search is not going well. If you post your city and when you need care there may be someone on this forum that has an opening.
