Sorry, have to brag....
We just got back from a trip to Europe for my sister's wedding that involved 24+ hours on planes and in airports in each direction. I was a little uncomfortable NIP before, but I am proud to say I am now a total pro!
On the plane it's pretty easy, because people tend to keep to themselves anyway. In the airports, I started using a cover, but by the end of the trip I didn't even bother. DS doesn't like the cover, and it was just easier not to have to dig out one more thing.
I got no comments of any kind, my baby was fed and happy (I think he even had a growth spurt from how often he wanted to comfort nurse on the plane).
It was a little like learning to swim by being thrown into the deep end of the pool, but I now feel like I can feed my baby anywhere!
Re: NIP FTW!
@Adanessa- I was nervous, too, but it turned out not to be a big deal. He ate and slept the whole time. The plane is like a giant white noise machine, and we put him in pjs before, so he was sleepy the whole time. We also brought a boppy on the plane, and let him sleep on that, which is his favorite napping spot.
In the airports, I just found the most private seating I could find and went for it.
I wore nursing tanks and loose fitting shirts over top, so I was covered without having to use a nursing cover, which my son hates.
My LO is younger than yours, but for us it really turned out there was nothing to worry about. Good luck!
