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

Growth

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! 
(This will remain same during 9-11 months)


Read here some fun-recipes to keep your baby healthy and chubby!

• Uses hands to wave goodbye and to point out things

• While holding the furniture, he/she can squat or sit back down
• Can sit confidently without any support
• Might try to crawl up stairs
• Can even pick small things with finger and thumb (pincer grasp)
• Uses both hands to hold or do two different things

Sleep

• At the age of 9-10 months, babies tend to sleep for around 13 hours 30 minutes a day, which includes 11 hours of night sleep and 1-2 naps during the daytime

• Doesn't know how to wave a hand or shake head
• Doesn't point out things or seek help
• Forgets her/his already learned skills

• No interest in sounds
• Doesn’t respond or react when own name is called out
• Doesn't understand any instruction

Based on my research and personal experience, I have tried to be as accurate as possible, however, if you have any disagreement with these milestones, do consult your paediatrician.
