4 month old doesn't coo or babble

[EssJayyCee]

Hi,
My baby doesn't coo or babble yet.
She had a day or two where she tried at 2 and a half months or something but not done it since.

She is doing other things like smiling, laughing, rolling front to back, grabbing things and putting them in her mouth etc
But she just doesn't try to make sounds.

The only sound she does is a squeal at the dog.

Is this okay or should I be worried?

Thanks

It's fine. My eldest babbled for a week at about 2 months and then said absolutely nothing until she came out with proper words !

@EssJayyCee how is ur baby now
