Contact Early Childhood Alliance in your area or check a government website for childcare centers. There are multiple that over 24 hour care. You might also consider getting a nanny that can stay with your children overnight. You can still put your kids into bed and do your night time routine. Have the nanny or babysitter stay with them overnight. Nanny can get them up about the time that you are returning home from work. You can spend your morning with them eating breakfast. They will not even know you were gone.
As a side note, I have a special needs child. The daycare center I use is a 20minute drive from my house one-way. Although it seems like a long drive, it's worth when I know my kids have good care. You wouldn't have to use your family for childcare all the time, but perhaps contact them as an emergency backup for once a month (or something like that).
When I was married, my ex-husband used to work 3rd. My child didn't even know he left because he left after he went to sleep and husband returned after baby woke up. Even if you missed breakfast when they left in the morning, you would be there to see them after school, to make dinner, etc. It will all work out.
You need to follow your dreams. Figure out what makes you happy and finding the right babysitter or nanny will fall into place. There are nanny services you can use. Talk to your friends and see if any of them have college students needing some work. Offer them a room in your house and room and board to stay there overnight. Most students study into the wee hours of the morning. If you find someone responsible, you may not have problems with people coming over at weird hours, etc. Set your ground rules. Have a backup or two ready... like your sister and another nanny.
Many 24 hour daycares and babysitters have an extra room set up like a bedroom so that the child feels at home. My girlfriend has a bedroom, toddler bed, toy box and tons of kid stuff in a room set up just for her clients. There are cots she can pull out and two kid beds.
I have watched my girlfriend's kids overnight. I either put her kids to bed first or mine. It takes them forever to fall asleep all together... too much like a party...lol.
Don't give up on your dream because you're afraid of what "might" happen. Focus on making the most of your time. If you are not happy with self, then in the end you will suffer.
Many hospitals have employees work 10-12 hour shifts 3-4 days a week. In this way, you work full-time, have more time with your family, have more days off and you spend less on daycare. If you worked a 12 hour shift from 6am-6pm or 8pm-8am, you would still be there for one meal a day available to help get ready for the day or for bed.
