curious why u would want to stick to the 70 30 ration for long term? u are not strictly allowed to feed only 1 brand but people do that so that they’ll know if their babies are having any reaction to it, if u mix, u most probably wouldn’t know right? that said, u can feed more than 1 brand but give it awhile after u change to see how your baby reacts
Is there any reason you want to stick to giving 2 brands long term? I don’t think it’s a no-no, but it’s certainly an unusual choice 😅 you’ll need to finish both opened tins within 1 month too
Can try nan or enfamil
