Dave Called Mama on the Day before He Reached 7 Months

You can never predict what words that your baby will say and when he will say that. Yes, yesterday Dave just called his first "ma ma" words. My father-in-law, Mr., Me, and Dave were sitting in the dining-room. Dave were mumbled "ba-ba-ba-ba" for few times. Suddenly, "ma ma" came out in between. We were just stunned. Basically, it's just so unpredictable. It was good though. ^_^

He's 7 months already. He still couldn't sit by his own. He's pretty slow in moving. I am not sure if it's because of his body-weight or well am not sure.
