I will be totally honest with you. From my own perspective.
I worked many years in child care then went to college for several years.
Once I married this husband and moved to this town I worked as a nanny for 3 1/2 years for two families, one mom brought her son over each day to the other family's home. One was the department head of the college of nursing and the other was one of her tenured professors.
Then I worked in the field of Developmental Disabilities. In group homes, work shops, the community in their own homes, with married couples, single parents, children, etc...many different settings.
There have been odd jobs in there too but for the most part that was my brief work history.
I can honestly say I hate staying at home all day. It is not fulfilling, it is frustrating and annoying. The house is never clean like it was when no one was home all day making messes. The dishes never get completely done, the carpet needs to be cleaned every other week, i do not get any time to sew or do scrapbooking, nothing is ever completed or finished for more than 5 minutes.
I miss adult conversations that are about life topics. Talking about work things or school lectures. I miss being told I am smart and funny and that everyone wants to be around me. I get tired of being unappreciated and ignored. I miss having friends that are just "my" friends. Who chose to be around me because they like my personality. Those warm fuzzies that make us feel good inside about ourselves.
I think that if you love your calling in life that you should consider changing back to a job similar, if not the same job, as you were doing before. You said you loved it until this new job.
I know that you may totally enjoy the time at home but it does get boring very quickly. Your children will be in school all day and will not be there. Even the youngest will be old enough for a pre-school program at 3 yrs old. Then she will be in Pre-k at 4. In my area those are both full day 5 days per week programs. Even Head Start was 8-2 5 days per week.
I think if you want to stop working and never return to nursing then it may be just what you need to do.
If you truly love being a nurse and will miss it terribly then stay being a nurse but change to a different job that you will love again.
Even if you stay working for the next year change jobs of possible. You sound like you really don't like it.
