Oh mama, I can understand your concern, it's completely natural to feel a little worried when we compare our little ones' development. At 1 year old, some babies do take a little more time with babbling, but since the information you shared is something worth looking into, it would be best to bring it up with your paediatrician just to get a proper assessment and peace of mind. The fact that your baby is responding, laughing and making sounds is lovely to hear, but do mention specifically about the lack of "mama" "baba" sounds to the doctor so they can guide you better. Wishing your little one all the best, mama, you are doing a great job looking out for your child.
