Well you can go ahead and complete your licensing.
But per your being pregnant, you need to have an "assistant" probably.
You have 2 kids, (I assume the 6 year old is in school), and your infant, will count too. And there are ratios per children to adult, when having child care. And if you exceed that child:adult ratio, you WILL need to have an assistant/another provider.
I would hesitate to hire a pregnant Home child care provider.
The woman would need to go to pre-natal appointments, and who knows what will arise while she is pregnant or how it will impact her activity levels etc. And once she does have her infant, then what? How will that impact how the other children in her care, are cared for and supervised?
And, if/when a pregnant Provider needs to close, then what? The clients will need to find another, care provider.
Your Husband taking paternity leave... per your idea- well can he even do that with his job? Will he do that, AND handle your daycare responsibilities? For how long and how many weeks???? And will the clients feel fine about that? And how will that affect their kids?
Then, for you: CAN you, actually take care of other kids, while caring for your own kids AND an infant???? You had a resale business while pregnant and had your other infant... but that business does not entail- talking care of other people's kids. Just yours.
Me: I did childcare when my eldest was a Toddler, and even while I was pregnant with my 2nd child. I did that until I was 8 months pregnant with my 2nd child. THEN, I quit. My tummy was just too huge for me to lumber around with and I was tired and I was needing to be off my feet. But I was only taking care of 2 kids. Toddlers. Being I already had those clients/kids even before I was pregnant, the client and their kid stayed on with me, as the babysitter. This was at my home. But once I was 8 months pregnant, I told them I can't keep doing it. And I stopped doing child care.
I had had a c-section as well with that pregnancy.
Or an option would be: to do your daycare on part-time hours. Instead of ALL day watching other kids, and while you are pregnant and after... just do half-days or something.
The thing is: you do not know how you will feel per your pregnancy or what will arise. And you will need to take time off for prenatal appointments etc. And clients, need a regular schedule that they can rely on weekly. So how will that impact, them?
