Finally we found the one! – I have to mix feed due to supply issues, and I had tried S26, Aldi, Aptamil, Blackmores and Novalac and they either gave my son constipation, made him super gassy or spewy. I was seriously at my wits end because I'd wasted so much money on these formulas! I decided to try this one and hallelujah! He doesn't spew anything up at all, his poos have gone back to normal and he's happy and healthy. Not to mention he sleeps 11 hours straight at night and he's 12 weeks old! I couldn't recommend this enough!
