11 puppies eh? That is a HUGE challenge!!! My 2 boys came from a litter of 11 and I visited the mom and pups when they were very young - a woman from the shelter was keeping them in her home prior to when they were old enough to adopt out.
She basically had her entire dining room gated off in a large pen (it was a tiled floor). Papers and puppy pads covered the entire area, and she had one large bowl to feed them in and another for water.
Here's the reality of 11 puppies: You will spend a lot of time picking up puppy poop. When they wake up from a nap, they will all poop. Within 1/2 hour of feeding, they will all poop. When you turn your back, they will poop. They will want to eat the paper and puppy pads and you will be cleaning up after them pretty much the entire day.
Keep a gross of paper towels handy, as well as newspapers, puppies pads, a large garbage can, broom, mop and cleaning supplies on hand close to where you keep them. Don't try to keep them in any room with carpet or you will be replacing your carpet.
Do NOT leave food out for them all day long. Get them on a regular feeding schedule with a high quality puppy food. If mom is nursing, puppy food won't hurt her. Ask your vet specifically about how many times to feed and how much.
They will spend a lot of time playing with each other but you should also have some sturdy toys on hand. You should also give mom a means to escape from them - 11 puppies are hard to handle by anyone, their mom included.
And yes, you want to handle them and love on them. We climbed into the pen (watch your step!), sat on the floor, played with them, put them on our laps, brushed them, and generally got them used to people. The more contact they have with people, the better adjusted they are when they are adopted out.
After seeing my boys and their siblings at that age, my heart goes out to you. While this will be challenging, it will also be a blast! 11 puppies together are an overflowing barrel of fun!!
