My baby is still not babbling. I am worried. When should they start blabbing mama or papa?

Don't worry too much about it, different children start babbling at different times. My friend's son started babbling at 9 months while her daughter started at 6 months. Songs, stories, and talking to your child everyday are ways to encourage verbal development. I, myself, didn't start babbling mama/dada until I was 1, apparently. Now my mom says I can't shut up hahaha.
