Happy Birthday Sweet Sierra!!!!! Our baby is 3. Where has the time gone? The family had a great time celebrating Sierra's birthday but the real party is next weekend. Stay tuned for those pics. Turning 3 has been a great milestone for Sierra. She has grown up in so many ways as she hits 3. She has given up her pacifier without a fight. She was potty trained months ago. She has moved up from Mom and Me to Kinder Gym I, and her speech improves with every passing day. She is a sweet girl with a great sense of humor. Happy 3rd birthday Sierra Bearra.
