2.5 months eating often

My LO is 2 MOs and eats every 2.5 hours, he use to eat 3-4 hours and these are 4oz, sometimes 3oz. There's even times he needs 1 oz just to go to sleep. With my first born she was eating 3-4 hours 4oz, and around 3 months I gave her baby food just a little bit and she loved it and disgusted it very well, I also gave her little tiny spoon of cereal in her bottle. But this time i'm getting judge when i mention it to anyone with trying to do foods with my Lo at such young age. I know their too young but I feel as if i know my kids better than anything and I know when they are ready, and at the time I did mention it with the dr and he said it is young but not too many feedings of baby food and should mainly be bottles of milk.

Any advice to anyone having this issue? LO not being full or being hungry too often? What did you do
