"The days are long, but the years are short."

You will be amazed at how quickly your baby changes from week to week in the first year. Most people plan for newborn photos and possibly a first birthday session, but don't forget about the in-between time when they are a little more filled out, are smiling and can do tummy time (about 3 months), and when they are sitting up and very expressive (6-7 months).
