"Bye Dada"

Kayden said his first two word phrase this morning!! He has said "and this", "and that" and other similar phrases but this was the first 2 words he said that both carry meaning! I was so excited:-) Kyle was getting ready to walk out the door and he always says "bye bye" and waves but this morning he waved and said "bye dada". Daddy and I couldn't believe our ears and thought maybe we were both hearing things but then he did it several more times, once daddy got in the car, as we were walking down the driveway to take Fifi to potty at the park, and as daddy drove by us on his way to work he yelled it to daddy.
