Weight is gud according to birth weight... And give only bm till 6 months frequently... if possible. .. ... only Bm is necessary for 6 months... Baby will gain weight slowly....

Yes it totally depends on the baby...

I agree with Srilu,

If you are having doubts,you can ask with your Paediatrician and clear your doubts...

Then try to talk with your baby for more time,show her the objects,colours around her and jus give instructions to get like get the blue color bottle,show the red chair...jus am telling the examples...
If you describe it she will get interested and also can learn colours...

My son was also slow in talking,I jus used to do the same way...
Teach alphabets,numbers,words,simple rhymes...

Main thing is that you need to sit and talk with her...

And next time when you go for checkup ,jus once talk with your Paediatrician regarding talking and clear your doubts...

You can consult with the Dr and clear your doubts...

Can u share image?

Give medicine as prescribed by doctor. Baby will recover soon.
Crawling time have to watch babies carefully. Because they touch the ground and they insert their fingers inside. Most of the infections come like this.
Clean her all toys in warm water every day then give. Observe this age they put small objects can put into their mouth.
Always check her surroundings with out small items and sharp items.

Baby should b healthy with proper weight , now weight is good .Chubby or fatness is not important. As ur bm is only source of nutrition for baby till 6months, continue having healthy diet , with lots of water.

2 n half months? It's absolutely normal...it will become normal as baby will grow ...but for 2 yrs age kid u should consult once to the doctor they will suggest u after the assesments....

Don't worry,
Gradually will speak...

Initially they speaks like that only,later you need to be ready to answer your baby's simple questions...

My son too was slow in talking,now he will be asking questions ...

Give some instructions kind like get the bottle,book,ball,show the things and be pointing it,he will be knowing and tell in a way like describing the colour or size of the object...
So that he can learn colours and knows the objects names...

You need to sit with your baby and speak for sometime...teach simple rhymes...
Already your baby is speaking,so no worries...

This age they will start with small words. Slowly they recognise the words and they will try to speak. Always talk with him and tell again and again. Mingle him with your family members. Some alphabets ,some letters they cannot pronounce. Show objects and ask him about colour, name, number etc.
He will speak normally after few months. Don't worry. Try like a teacher. Every month you can observe their progress.
