I think, no matter whether your children are in a day home, daycare, or you have a DH, or what, it is always hard to leave your children, especially at first. The key is do you trust them? I wish my day home provider had a webcam set up, I would love to be able to see what my children are doing. You miss so many things. My day home provider would write me note everyday in the beggining, that said what they ate, diapers changes, what they did, cute things they said, what they palyed with and I loved that, because that was what I missed most, knowing all the little details.
I know this may not work in a DH situation, but the agency my provider is with requires a written report for every injury. The first provider we had, my child fell down the stairs while my husband was there. The gate was not secure and he leaned on it, he only fell about 4 steps and my husband caught him, so he was not injured, but the lady refused to install a proper gate bolted to the wall, did not notify the agency (I did), or do any of the paperwork, needless to say we switched proveders. The lady I have now (for 2 years) tells me, and records every tiny little thing, that is barely an injury, she would reprot a stubbed toe! but I do trust that she will let me know anything, whereas the first lady, who knows, maybe there were incidents that we never even knew about because she didn't tell us or report anything. I would make sure the DH knows you want to know everything that happens. Because things will happen, no matter how careful your DH is.
The first few weeks will be the hardest, but it will get easier and you will really enjoy the time you have with your chidlren even more.
