Check out La Leche League Peru's Facebook Page and LLL Peru. Most of the LLL Peru's page is in Spanish, but they do have a monthly English meeting as well.
One tip to remember is that speaking Spanish will help you greatly. You'll be treated differently than if you speak English all the time, it'll help you assimilate, and you'll be able to communicate easier. If you're looking to learn Spanish, the two programmes I recommend are Synergy Spanish and Speak From Day 1.
