How can this be? My Moose is 3!!

Moose,
 You have been such a joy since you were born (after that delivery, that is). At 9lbs. 8oz. you were our Moose; a big boy by any standards but still a little baby to us.
 It was as though you wanted to be as sweet as pie after putting me through such pain to get you into this world! You made your own routine quickly, eating every few hours (whether food or bottle). You were routine in so many ways: rolling over, walking, talking, teething. God knew that I needed someone laid-back while I finished school.

 You have always adjusted well to life. Whether going to college activities with me, switching day care, staying home with me, moving to Virginia, moving back to Nebraska, getting a new baby brother, moving again. Always it's seemed that you say, "whatever" to everything life throws at us.
 You have always been so sensitive, getting upset when I cry (or when another kid at the park is getting yelled at). You love fiercely (sometimes too fiercely when it comes to your toys). You may be a big boy but you never fail to give me a kiss or hug as I request.

 I may not understand you sometimes, but I know you're so smart. ABCs, 123s, colors, shapes - all within your range of knowledge. I'm so proud of how you love to create paintings, read books, and recreate the movie Cars with your little Matchbox cars. You never fail to amaze me!

 I hope that this birthday is one of so many more to come, so many happy times to be in your life. I want to share with you all the love that you have given me. Never a day goes by that I don't thank God for you - you are such a blessing. You bless the lives of any that know you, truly.
Thank you so much and happy birthday, my big boy!
Love,
Mama
