Ah mama, congrats sa baby mo! At one month pa lang, mas better pa rin to exclusively breastfeed if possible, pero I get na kailangan mo mag-work, a few of us moms had the same struggle. For sensitive babies, ang popular dito sa amin is Similac Pro-Sensitive or S-26 Gold Sensitive, maraming moms swear na okay sa kanilang babies with sensitive skin, pero honestly kailangan mo talaga konsultahin ang pediatrician mo kung ano specifically ang sensitive skin niya (milk allergy, lactose intolerance, or just irritation?) kasi iba-iba ang remedy. Abangan mo rin kung may rashes or digestive issues pagsubuan mo yung formula para sure. Good luck mama, you got this!
