My baby is 4 months as soon as I switched her to this from soy her acne and constipation from soy went away this is a great product for kids who are milk and soy intolerant my baby went from gassy and constipated and colic to just being happy it's also the healthiest plant based formula that exists we tryed loulouka and even with the healthiest milk formula my babes stomach couldn't handle it else has seriously been a life saver since my breast milk drying up at 2 and a half months was hesitant to use when it said 12 months plus but when I read that other infants use it I felt fine about it and also I read they have a different infant formula that's about to come to the market my baby has been on this for about a month now and literally all problems went away the only thing you way notice is your little one will be more regular then normal the first week you switch but other then that the formula is so good an adult could drink it It also has no weird smells or tastes like the other formula products in the USA other then homemaking your own formula this is the healthiest one which is great and if you have boys that are milk intolerant this would be best since soy milk creates estrogen my baby has been on this a full month if any complaint I will write another review later explaining it ! In the photos below is a before and after because her acne went away after using this Formula
