The mil who wants to occupy center stage all the time

my mil just pounces on every opportunity to talk and goes on talking non stop. Let me clarify that this is not out of lack of ppl to speak or loneliness .She has lots of friends/family/maids/whatnots to talk through the day.

Back in the day when I was in better terms with her, I was feeding my kid who was then 8 months old, and she non stop spoke for 45 mins- without even stopping to catch her breath. I had to then start talking loudly to my kid to make her stop and give me the chance to speak to my own daughter.

Another incident - at the time my daughter was around 1yr one of my cousins had come and she asked the baby things like 'what all stories do u know'. Obviously the baby was too young to speak, before I cud even open my mouth to answer - pat comes my Mils reply that the baby knows ' crow and the fox' and the went in for 5 mins blah blah blah. She didn't give me a chance to speak at all. Basically, I don't get a chance to talk in her presence -she elbows me out and makes sure she gets all the attention.

A lot of times she does it subconsciously I feel.

Even if ppl are explicitly looking at me and talking, she butts in gives her useless opinions and makes ppl talk to her.

i think she has a "I have to talk all the time and other ppl shud also talk only to me" disorder.

living with her for 5 years, it makes me go nuts.

This seems to be her basic nature- that conversations and the world should all revolve around her.

Any tactful way of showing her how obnoxious she is other than having to out-shout her all the time?
