Children grow and change SO quickly. Don't let the years pass you by without documenting those sweet moments. From the big moments like a birthday or the first day or school, to the little moments like a sweet snaggletooth mouth or a new sport or hobby, there are a million reasons to have portraits taken of your little ones, and very few reasons not to.  As an adoptive momma, I so wish I had photos of my children when they were tiny. Kids are only kids for a little while, so get those photos taken while you can!
