I'd really encourage you to find some stretching exercises, IMHO.

If you plan on practicing the guitar in the medium/long run, you want to be able to get past some of your limitations. There are a number of great guitarrists out there with smaller hands, and I believe they have learned to get past that.

It's just something we all struggle in the beginning, but it's actually not a matter of size, it's the stretch you're after..

So just practice some stretches and you'll see gradually that your fingers will reach farther and farther.
