Hi mama! Honestly, mas better kung mag-consult muna siya sa OB niya dahil the asthma medications she's on might affect kung anong formula or milk is best for her, some moms I know had to switch brands kasi ng pregnancy cravings or sensitivities, but with asthma it's a different story talaga. Ang doctor lang ang makakaadvise ng safe options for her specific situation, pero congratulations sa pregnancy!
