K.B.
I know a woman who had 7 pregancies in 5 years. She had 4 under age 6. Another couple had 4 kids in 5 1/2 years(all accidents they would tell people???). The first couple allowed extended family and friends to help out quite a bit, though there were divorced grandparents and that was a bit awkward at first. They all lived within 20 minutes of the family.
The second family was military and moved right before number 4 was born. They picked a church fast and put in a prayer request for help, stating their situation and their needs. I was so impressed by the husband asking for help because he had to work and leave town for training. He was a macho guy sort of, but realized his wife could not do it alone.
I have to say, that church came through with babysitting, meals, cleaning, driving, mowing, and even fixing the car. I have never seen strangers come together in real life to help someone who can not possibly return the favor.
I did not do a schedule with my child, but I sure would with 3. And I would insist on a nap/quiet time. I would not let anyone give the children caffeine(tea, cola, frappes).
Congratulations. :0)
