Hey gipson71,
You wouldn't even have to stop for that long, you can stop for a few weeks and almost go back to scratch. I've picked an acoustic for over eight hours at some jam sessions before, and that can wear most fingers out. I'm not saying for you to play for eight hours, but you definitely want to play enough to keep your callouses. I try to pick a guitar at least once a day, so that my fingers stay in good playing condition.

Most of the gigs I play last 4 - 6 hours, if I let up for even a week I have to play with sore fingers the next night. This is the hardest thing to get past, if you've built your callouses you're ready to learn anything. You don't have to play for hours on end, but play enough to keep those callouses. Also be aware that as you try new concepts, and techniques, callouses will show up in other places on your fingers. If you're making bars, starting to bend strings, even other chord positions will put callouses in other places on your fingers.

After a few months you won't even notice them, unless they aren't there due to a long break. Don't over do the practicing, but keep doing it daily. If you have to take a break, I wouldn't go any longer than a week if possible. You will still notice that you haven't played in a while, but it shouldn't take as long to get back to where you were.

Everyone else has already answered your question, about a lack of feeling in your finger tips. I just wanted you to know the importance of keeping those callouses.
