My baby has always had bad gas even worse gas on breastmilk so I completely switched him to formula we had used similac Sensitive for a while and I noticed that his poop is not as mushy, he’ll only poop once a day, still seems gassy at times, seems like he’s constipated, occasionally fussy but mostly just witching hour. We tried the efamil gentlease for 2 day’s because we ran out of it I hoped to try it for a week and I noticed his poop was green and runny, popped more than once, had less gas but still some, also occasionally fussy but mostly just witching hour. Which one is better also I use the dr browns bottles, I use the pre mixed liquid, and use gripe water sometimes to help with the gas. After we ran out of the efamil we finished off the similac that we had and now we’re trying efamil again this time we will be trying it for a week and sticking with it if it works out better
