Powdered formula causing wind. Ready to feed a fortune.

[Lottiebugz22]

My baby seems to tolerate ready made formula (Aptamil) better opposed to powdered formula but it's costing me a fortune. Can anyone suggest a powdered formula for a windy baby.
I've tried aptamil 1st
Cow and gate 1st
Aptamil reflux
Cow and gate comfort
Sma 1st
Hipp organic 1st

Stop changing formulas. They take 3 weeks to adapt to a new one. Have you tried adding a probiotic in? We use HiPP organic and Optibac powder in one of LO’s feeds.

Are you making them correctly? Powder after water? Powder before water means they aren't diluted enough.
