Ma-ma or Mama?

My little boy says "Ma-ma" or is it "Mama?" It's debatable. Lola was all about the "da-da" sound early on, which Dan was sure she was associating with him. Now that Mac is saying "ma-ma", Dan assumes that all I do while he is at work is try to get Mac to say "Mama"... but Lola is sure that while Dan is at work, he plays the bongos all day :) Either way, love my happy little Mama's Boy.
