Cereal or No Cereal?

Brittany
I would like some opinions on adding cereal to bottles. My little girl is almost 3 months and other than some minor gas issues she sleeps well and is a very happy baby. She was born early and was only 5 lbs, but she's growing right on track even though she's smaller. 
I've seen so many different articles and hard so many different people say to start adding it around 3 months, but then I've seen/heard just as many saying not to add it at all. 
I know, I know my baby best and trust my instincts, I would just like you ladies' opinions! 
TIA 😊
