baby should b just happy and healthy.. he should b active and achieve all his milestones.. this is what matters.. you should not b so much concerned about the weight factor..

Thank you everyone  for answers. i now feel relived.and he is very active as you said priya.

Your concern must be that your baby does not fall sick often. Watch out for that. Like the other mums said, a chubby baby does not mean a healthy one.

I agree. Chubby doesnt mean healthy. Baby should be active. My baby was lean and that made him more active and flexible. Sharing a good read <font color ="#3b5998"><b><a href="http://app.babychakra.com/article/1100">The Ultimate Height and Weight tracker for little Girls</a></b></font>

9 kg at 9 months is good. sone babies r lean...some r chubby. but it doesnt mean ur baby isnt healthy.
