I, too, have nursed 2 kids all over WDW and nobody has ever said anything to me. I did utilize the baby centers if I was close by at the time, but I viewed them more as a luxurry than a necessity.
FWIW, I have only ever once anywhere had somebody say something to me while I was NIP-- I resonded by telling her (yes, it was a woman) that I couldn't care less what she thinks and went about feeding my daughter. (Her comment was "You should know that EVERYBODY can see what you are doing.).
That being said, I have had comments made to me about other nursing moms more frequently. I agree with a prior poster that I think it is rare that anybody actually approaches the nursing mom directly.
I didn't NIP because bf'ing did not work out for us due to my medical issues and I was too self conscious when I was nursing but it truely amazes me that some women can be so ridiculous when it comes to feeding a child. Seriously, you see more breast from a bikini (in most cases) than you do from feeding a child. I hate seeing moms feel they have to feed their baby in a bathroom because they fear what others may say to them. I talked to a new mom one day at Target who was feeding her baby in the bathroom (I waited until she was done and came out of the bathroom) and let her know that if she wanted a secluded place that she could use the dressing rooms for a cleaner more comfortable option. I made sure to let her know I was not telling her she had to but I felt so bad for her trying to nurse in that nasty bathroom and wanted to offer her the knowledge I had for Target.


I think being a parent is often (not always!) the beginning of the end of caring about what other people think!
Don't worry a minute about what other people think about you nursing your sweetie -- or else you'll find you're worried what people are thinking when your 2yo has a meltdown in public. Then, when she's three, she'll belt out a cuss word in front of your MIL. At four, you'll run into your pastor at the store, and your daughter will say hello while she's got a finger jammed up her nose. When she's five, she'll be the only one at kindergarten graduation who shouts, "I'm bored!" and walks right off the stage. And you'll realize, as each year passes, that people are going to judge you and your parenting skills and choices. Don't. Let. Them. Bother. You.

It took lots more time and planning and I really felt for the other traveling bottle-feeding moms!
I'm glad to hear that most people haven't had any problems NIP. Now, if only I could figure out the logistics of keeping her entertained in the airport, cramming all of her stuff in our luggage, and make a final decision on what stroller we are going to take.
