Air India Express — Worst experience while checkin with infant & child

I has the worst ever checkin experience in in my last travel from Jaipur to Mumbai on 7th May 2025.
I was travelling alone with an infant of 7 months and a kid of 10 years.
There was no co-operation in the Jaipur airport of making a priority checkin.
The most painful part was that i had to spent almost 45-1hr at the checkin counter.
Reason being my Checkin luggage was 33 kg instead of 30kg.
"Bhumika" who claimed herself to be manager over there was not even ready to consider 3kg inspite of requesting here multiple times that i was travelling with a kid & Infant.
Also my hand baggage was also not a single gram extra (dot 21kg).
At the end i had no option but to pay INR 1950 and leave.

This was never expected from "Tata Group".

Just wanted to understand is this the way you consider the situation where 3 kg excess could not be handled inspite of the fact that a mother is travelling alone with a kid and infant ???
Worst ever experience.
