My girl use to drink S-26 since she was borned, i've just help her to change to beanstalk within 2 weeks time. Maybe she is to use to S-26 ( milk is very sweet & thick), so I still put 1 scope of S-26 with 5 scopes of beanstalk to make her 8 ozs of milk. My girl doesn't drink with beanstalk alone( too watery). Her "booboo" was much better than b4 ( soft & very moisture)
