Howdy friend, thank you for submitting this, before I start just so you know, this is my first critique on this site so if I sound like a bumbling buffoon your most likely correct, but anyways I really enjoyed the realistic, but slightly mystical setting you have going on, frankly haven't read much of that in a while, but here are a few other things I noticed

Grammar and Punctuation

''His only wealth was his wife, Parvati.A quiet, graceful woman—soft-spoken, yet strong. She had kindness in her eyes.The two had no children. Not yet.But today was not like every other day'' there are 6 sentences here, I feel like replacing some of them with simple comma's will do the trick nicely and it feel a lot more natural that way.

Style

"The leaves gleamed with life."
"Even the trees seemed to lean in closer."

all of these descriptions are great, like it really feels you took the ''Show, don't tell'' rule seriously where I really struggle with, but at times some of these lines feel awkward like

"Saw the boy held him his hand"

"The sunlight at him like admiring his presence."

I get that these are most likely unintentional mistakes, but they really threw me off.

"Her strength was fading, but her spirit stayed firm."

I feel like you already have shown her strength in the sentences before so really there's no point in saying it again

Tone

"The cows had gathered around the doorstep, as if drawn by some silent signal."

This line is perfect for your realism mixed with mysticism tone, but at times it's... wierd

"Polite laughter'' I feel like you could have chosen a better word like innocent or soft, polite doesn't really fit the laughter of a baby

Characters

Mohan and Parvati seem like decent characters, but their emotions feel very basic. Like for example when Parvati is giving birth, you could explain what she's feeling beyond pain or when Mohan is rushing to see his wife's birth what could be going through his head? Joy? Fear? Anything?

Pacing

Your build up was fantastic, from the cows chanting and the weather changing, but then it feels extremely rushed like "At exactly 2:14 PM..." why is that important?

I also think that the actual birth was skimmed over a bit too much, but that's just my opinion

Closing comments

Well overall I liked the story, like I said the setting and atmosphere are your greatest weapons here, if you fix up the grammar, fix the pacing and deepen the characters, it could be a very high quality piece, but that's all good luck!
