4 Months Old, already!

They are getting so big!  Each day they are doing new things, whether it be batting at toys in front of them, smiling more, grabbing my hair and necklace, making talking noises, focusing directly into your eyes, nuzzling into our necks or just being more and more alert for longer periods of time.  They are so much fun to watch grow and it really is unbelievable that they are already four months old!  Their personalities are starting to come about and I spend much time wondering who they will become.
