when should babies start babbling
Rating Newest Oldest. Best Answer: About 2 months. That's when their smiles become real (thus, not reflexes, and genuine responses to you/amusement) as well. But of course, as others will most likely say, all babies are different, and anywhere around 2 months (be it a month before or after) is still normal. However, babbling usually comes later, between 4 and 6 months.
