What's your Take on this?

Frankly, and I know most people are going to disagree with me, but I would keep the child. The one major thing I get from that email is that they're trying to work with you. Originally, they wanted 7-6 everyday, right? You said that won't work, and now they're trying to speak to their employers in order to give you what you want. I'm not saying you're being unreasonable in your opening and closing times; you are perfectly within your rights to make whatever hours you want. But they recognize the problem and they're making an obvious effort to make it work, and that can't be easy with many employers. Where do they work? There's no way my husband, for example, would be able to change his hours like that. He manages a retail store - if the store opens at 8, for example, there would be nothing he could do if he couldn't drop the kids until 8:15 or 8:30. There's no room for flexibility.
They obviously don't realize that all the schedule changes might not work for you, and might make it more difficult regarding your daycare's schedule and the other kids, etc. But they're trying! They may need some suggestions as to ways they could try that might be easier for you, but I guess my point is that they're making an obvious effort. If it was me, I'd appreciate that and try to work with them. If you can't come to something that works for both of you, so be it, but I'd do my best to figure out a schedule that works for both of you. They obviously want their child in your care, so they'll do all they can to make it work. Sounds like a considerate client to me, just a bit misguided as to how to help the situation.
