Advice on Formula that has worked until now

Hello everyone,

I'm a FTM and it is my first time posting here. My baby is 12.5 weeks old and has been exclusively formula fed since 2 weeks old. We have done Similac 360 because that's the one that has worked the best. We tried to slowly switch to Parent's Choice around 5 weeks but the colic and fussiness wasn't worth it. So Similac 360 it has been.

He tolerates it well and has regular BMs but lately he's had A TON of gas. He gets super fussy about 20 min after feeding and isn't finding relief unless he kicks out a lot or is held repeatedly in the "squatty" position. I give him gas drops (Mylicon) and it still happens. Poor thing has huge toots when he finds relief and it's happening at almost every feeding whereas before it didn't happen at all.

Pediatrician doesn't have any insight because Similac 360 is what is recommended at her practice.

Baby has also recently begun teething in case that may make a difference. He's eating as much as he always has via a bottle; currently 15lbs so we're not concerned about gain. He's just really unhappy and uncomfortable, particularly in the evenings.

I'm considering slowly switching over to the Similac 360 Sensitive to see if it helps but wanted to see if anyone else had experience with an issue like this.

Would love input to help my little one be more comfortable!
