Sophia repeated as the most popular name for baby girls in 2011, one year after knocking Isabella out of the top spot, according to the latest rankings released by babycenter.com.

Aiden, meanwhile, ruled the boys' list for the seventh year in a row.

The other Top 8 choices for boys this year are: Jackson, Mason, Liam, Jacob, Jayden, Ethan and Noah.

According to the babycenter.com survey, cellphones and social media are playing a larger role in baby names.

Forty-seven percent of moms surveyed used their cellphone to decide on a name, up 40 percent from last year. Half of moms revealed their child’s name to friends and family using their mobile phone, and two in five moms shared their baby’s name on a social networking site within minutes or hours of giving birth, according to the survey.
