Starting to do anything that is totally new is overwhelming till we get the hang of it and daycare is no different. It gets easier once you settle into a routine. At the same time the novelty can wear off quickly and what seemed like a good idea now comes with pitfalls not considered before such as lack of adult contact, lack of time away from our own children, wear and tear on our house, etc. If you can identify stressers and find a solution for them then you are more likely to start to enjoy doing home daycare again.
At the same time it is not wrong to say you made a mistake and really want your life to go in a different direction and then make plans to do that whether that is going back to your old job, moving on to another job outside your home, reducing the number of children you care for so that you can go out more or adding the maximum number of children so you can worry less about paying bills.
