Pearson turned 1 on February 20th and decided to walk the same day. Now she is very much mobile and already strong willed. Learned "no" pretty quick. Presley is 4 1/2 and surprises us everyday with her quirky intellect. So much so that I forget sometimes she's only 4 which is fine now but I'm afraid when she's 13 going on 20 won't be so funny. But the girls are at an age where Big Sis is teaching Lil Sis things and it's so much fun to watch them grow and learn.
