When does your LO respond to his/her name? Mine is almost 8 months but doesn't seem to respond much when I call his name. Should I be concerned?

Between the ages of 5 and 7 months old, most babies respond to their name being called. Babies are quite observant and at this age, their ability to associate sounds with objects or people is increasing. By 8-12 months of age, they can respond to simple commands like “no” and “stop.” At this age, they can also start to associate simple gestures with the corresponding sound, such as wagging your index finger while saying “no.” By 13-18 months old, toddlers are able to understand 2-step directions like “Stand up and hug mama,” or “Pick up your doll and put her in the toy bin.” By 2 years old, toddlers have a vocabulary of at least 50 words, which increases to 200 by age 3. HOW TO TEACH YOUR BABY TO LEARN HIS/HER NAME Simple: Say the name often whenever you talk to your baby. For instance, “Are you hungry, Eddie?” or “Did you miss Mummy, Stella?” Babies learn by repetition, so when their words, especially their name, is used often enough, they’ll pick up what the words mean. WHEN TO WORRY If by 1 year old your baby still does not respond to his/her name, it’s recommended to see a specialist. According to a study led by researchers at the UC Davis M.I.N.D. Institute, if by age 1 a child still does not respond to his name when called, he may be more likely to be diagnosed with an autism spectrum disorder or other developmental problem when he reaches the age of 2. "Whether or not children respond to their names by 12 months of age is turning out to be a good early indicator of developmental issues,” Sally Ozonoff, senior author of the study and professor of psychiatry and behavioral sciences with the M.I.N.D. Institute, is quoted in an online article published by UC Davis.
