Frequent visits to US by B2 Tourist Visa - Please Suggest

[jega]

I am a citizen of India currently residing in UK for onsite client work. I have my B1/B2 tourist visa (multiple entries) to US.
Here is my past trip details to US:
1) Visited 2 weeks during December 2012.
2) Visited 1 week during March 2013.
 

Now I am planning to visit for the third time this August 2013 for a short summer trip (1 week). The main purpose of my visit is tourism.
 

Please advise the challenges/questions I can expect @ POE and also any supporting documentation that is required since my trips were frequent.

Why do you think there would be any issues? I don't see any. As your past trips were for short periods, VO at POE wouldn't hesitate to Welcome you to the United States of America!!!!!
