It is great you want to breastfeed! You go, girl!
Pumping is kind of a pain; and having someone else give baby a bottle of breast milk may not cut it once baby learns you are right there--babies like the cuddly aspects of breastfeeding too! Also--no matter how good your pump is, it is never as good as a baby in maintaining your supply.
And when you are pumping you still have to deal with all those bottle-related issues--buying, sterilizing, washing, refrigerating, heating milk, etc, that breastfeeding at the breast just eliminates.
So I guess what I am saying is, think about pumping some, for those times you will need to be away from your baby, but I'm not sure I'd want to do that as the sole way of giving him/her breastmilk. But it's your call, try it and see what works best for you.
There are plenty of ways to involve your toddler while you nurse the baby. He can hand you a glass of water (maybe put it in a sippy if you think he might spill---plus he'll get a kick out of Mommy drinking from a sippy), help tuck blanket around baby's feet, hand you the burp cloth, help burp the baby gently, help keep baby awake during feeding if that 's what you need....
Also it was fun to sit and cuddle my older one while nursing the little one. Once your incision heals and you get comfortable nursing, you'll have a free arm to do this. You can read to him (especially if he holds the book), sing, tell stories, watch a video etc. Or just talk!
Contact La Leche League for more support ---remember they "wrote the book" on breastfeeding, "The Womanly Art of Breastfeeding". You may find it in your library, or sometimes the local La Leche League group has a library you may borrow from as well.
I think the generally-accepted time frame for avoiding nipple confusion is 6-8 weeks, but LLL can tell you that.
May you have a blessed birth and nursing experience!
