NOt that I'm biased or anything ...cough* cough* holistic nanny here :-)
I chose to become a nanny after my DS was born, and I needed to be able to do 3 things
a.) support us
b.) Do something that spoke to my heart
c.) raise my child MYSELF, (I detest daycares!!!!)
With the right nanny, you will be able to stave off most illness's, provide more individualized attention, keep you dc's in YOUR home, decide what when and where they learn.
your not restricted to daycare times and locations.
A good nanny will be VERY proactive in your childs care happiness and health, and will respect and honor YOUR families values.
You won't have to conform to the rules of a daycare setting.
Depending on the nanny you hire, you might even get a little bit of cooking and housework done.
There are MANY advantages of having in house help, you just have to find the right person.
I can't speak for others, BUT, I charge 15/hr. AND bring my 6.5yr old homeschooling ds with me. I am a FULL service nanny, light housekeeping, driving, cooking ect ect ect.....
for YOUR situation I would absolutely recommend that you consider a nanny with a child, and OR a nanny share, especially if you only need part time work.
