Over the past 12 months, you have seen a lot of changes in your child. From a newborn who couldn't lift his own head, he has grown into a child who can cruise around the living room on his own two feet and communicate with you, responding to your words and maybe pointing or using sounds in response. One day you'll probably glance into your car's rear-view mirror and think, “Wow! Look at that! How did that happen?” and then you'll smile and fall in love all over again.
