Gassy baby 😢

What bottles helped your little one with gas . Currently only have Dr. Brown bottles and they don’t seem to be doing anything 😩 he only drinks breast milk! some days he isn’t as gassy and does good and other days he cries forever and I’ll use the fredia windi to hell him fart which works most the time , he’s also on gas drops and probiotic . As soon as he gets all his gas out he’ll go right to sleep . So I’m hoping maybe changing his bottle that’ll help some . 🤷🏽‍♀️ worth a shot .
