I have three children. Two are teenagers now and when they were babies, nursing was total downtime; there wasn't anything you could do while nursing except watch TV, hum to yourself, or stare in wonder at the human being you made.
My third child, however, has been born into a world of gadgets and technology unimaginable the last time I brewed a beverage in my knockers. While I still spend plenty of time staring in awe, I have been pleasantly surprised at what I can do while nursing with the help of technology.
First, let me point out something that those who have never breastfed may not know: Breastfeeding is not as easy as you'd think. Sometimes you can use pillows or a brilliant invention called a Boppy (a crescent shaped pillow) to prop the baby at the booby bar and you'll have two hands free. Other times you need a hand to help keep stuff positioned properly (a ‘slippery nipple' is not just a cocktail).
For those one-handed situations... Kindle to the rescue. Not only does Amazon's godsend to bookworms allow you to read with one hand, turning pages with the push of a button, you can also shop for books and download new titles to the Kindle in about 30 seconds. Also great for nursing moms: the Kindle always saves your place in the book. Go, change a toxic waste diaper, scrape the spit-up from your shoulder, try to poop without busting your episiotomy stitches... it's all good. When it's time to feed the baby again you can pick up right where you left off.
If you can get two hands free...you can play vidya games! I've been able to play both Xbox 360 and DS while nursing. The trick though is to stick with something you can get into and out of quickly. Xbox LIVE Arcade games are a good example.
Whenever it's time to play moo-cow, I make sure that my Kindle, DS, phone, Xbox controller and Diet Coke are within reach.
