Out of the blue, Logan started calling me “Mom” instead “Mommy” the past 2-3 days.   I tried to convince him to change back, but he is very persistent and only rarely uses “mommy” now.  Since yesterday, he also started using “dad” instead of “daddy” too.  Logan must have picked up this habit at school, and with this change, he now sounds like a big boy.  I really prefer being called “mommy”, but I guess it is going to be a lost cause.  Our boy is really growing up!
