Hi mama! For the distilled water, you don't need to boil Wilkins anymore since it's already purified, pero dapat pa rin siya stored properly para laging safe, a few of us just use it straight from the bottle para sa formula. Sa purees, you're doing great actually! At 6 months ang weaning process is really about letting baby explore and get comfortable, so hindi problema kung once a day lang for now or if she refuses some days, basta consistent ka sa offering. Since paano exactly siya kumakain and kumikita ng hydration through formula and starting foods can vary, I'd suggest checking with her pedia just to confirm everything's on track kasi every baby's different, some of my mum friends had questions din and their docs gave them peace of mind. You're doing your best na, and FTM struggles are real, pero you've got this!
