Hello

Don't worry your baby will be OK.
Make sure he is breastfed very properly so that his immune system becomes stronger. Make sure he gains weight at a regular pace.

It's normal.

Hi if baby is sitting with or without support then it's normal perfectly

If your baby is showing all these movements then don't worry. Give her time and be patient. Babies take their own time to learn how to walk and balance

Hello

Hi that's very good weight, just breastfeed frequently ur baby for proper growth and development

Up to three months she gained one kg or 1.2 kg for month ...now for two months she gained one kg only

Hello
What I you baby's current weight and birth weight

Babies weight depends on their birth weight...

By 5 months babies birthweight could be doubled....

By one year babies birthweight could be tripled, calculate on that basis....

Every child will be unique in reaching there milestones....

You are so hurry I think,I can understand your feelings as a mom,to see your baby's first steps...

But she is too small,8-12 months crawling period will be,...based on that only babies stands with Support,.....some may skip this too,nd starts standing with support nd slowly will walk 2 steps like that initially....

So don't worry,keep an eye on your baby during crawling time,...be patient...take care of your little one .
