It wasn't the NIP that got to me when DD was that age, it was the length and frequency of feedings. We were basically nursing one hour on, one hour off and that will crimp anyone's style.
You can try to see if the baby will nurse in a sling. At least that way, you can get out and still nurse. Otherwise, it seems like after the first 6 weeks or so, things settle down a little bit and it gets easier. I stayed pretty close to home for the first two months. Now, I can predict life a little easier, so we can get out more.
