You can breastfeed anywhere discreetly. I do it and sometimes people don't even have a clue of what I'm doing until they want to look at the baby and realize the child is attached.

You can nurse as long as you and your baby feel comfortable. One year to four years, though most of us (my friends and I) stop (upon mutual agreement of child and mommy, usually) around 2 or 3 years.

Breastfeeding is a commitment, no doubt. It is absolutely the best thing you can do for your child, and we each want to do what's best for our child, and it also has bonuses for us moms too. It's very worth any inconvenience and actually is much more convenient than bottle feeding.
