Ideally fasting levels should be below 100 and post food below 140....once do have a check with doctor....

Yes babies keep changing in weight when they grows.

Don't worry,
By one year babies weight could be thrice of the birth weight...
Based on your baby's birth weight,weight is good...

Mentioned that your baby is active, healthy...so no worries...
Enjoy your baby's milestones...

Hi I have seen same problem in my first daughter. She didn't crawl. She was started moving in sitting position with the help of hands. She was slow in every activity. She started sitting after 10th month because of her head weight. She started walking after 18 months.
I was worried lot compare with other babies.
In between I consulted both pediatrician and orthopaedician they suggested some kids start slowly don't worry.
So don't get tension and consult both pediatrician and orthopaedician for your doubts.

@Chandni,

Don't make her to sleep for long in the day time...
As soon she finishes lunch try to make her to sleep for about atleast one to two hrs...

And in the morning make her to play,if she feels tired she gets sleep...

While going to bed,give one small glass of warm milk with honey,it gives good sleep...

At this age few babies will wokeup at night for atleast once for milk,give milk at that time...

Once they grows,sleep routine changes...

Hands n feet are cold sometimes bcoz of blood circulation..... Don't wry.... Check baby's other body parts like stomach or back....that should be neither too hot nor too cold...as u said thermometer is normal then not to wry........ Or for any doubts or for ur satisfaction u can ask to pediatric..

According to birth weight her present weight fine... Don't wry... Give healthy homemade food, , fruits, dairy products... If baby is active and eating well then don't wry abt weight...

After completing 3yrs... U can teach writing...Now u can start with colouring books, ,,teaching rhymes, and recognizing alphabets, , counting numbers, ,,

Make her speak.Try as if u r not understanding her actions .For e.g. if she wants water , make her say it .Dont Give water if she points at it without saying anything.Ask her fruits , colours, veggies name etc .Tell her simple stories & tell to repeat them .Teach 1 to 10 counting tell her to count don't expect correct answer.Like this way make her speak.From now onwards completely avoid understanding her actions

Don't think about thin and fat...

Doesn't mean that fat babies are healthy and lean babies are weak...

If baby is having ideal weight,having proper food,active means no worries...

Jus give her a healthy homemade diet...
Which includes fruits, vegetables,dry fruits,dairy products,pulses,eggs...

Avoid packaged foods,maida products...

My son also thin,but he is active...

Don't worry. It is happen 20 to 25 days in every new mother after delivery. It will stop depending on body type.
