A complete guide to baby’s developmental milestones from 9-12 Months

Now, that your little crawler has started moving around, you may want to consider babyproofing your house to minimize injuries. As your baby is on the wheels now, you have to be on your toes. You will also find your baby babbling or making a strong bond with the family members. 


9 - 10 Months 

Physical Milestones


At 10 months, the baby crawls very actively which means a lot of movement and a slight downward trend in weight chart too (as your baby starts burning more calories ;-)). Also, babies at this age hardly gain more than 700 grams weight. So, don’t worry, being active is a good sign!
