Aw momsh, totally gets it, ang hirap talaga pag laging gustong mag-feed pero parang comfort lang talaga ang hinahanap, hindi gutom! From what a few of us tried, pacifiers are actually okay at 1 month, especially kung breastfed ka kasi walang latch issue, pero mas better pa rin i-consult mo talaga with your pedia para sure lang sa baby mo specifically since may history na siya ng oversucking at pagsusuka. The pharmacy clerk might've been thinking of something else, pacifiers mismo hindi yung nag-cause ng gas, it's usually kung paano yung feeding position or swallowing habits; pero tama na bumili ka na from a trusted shop like Dr.Spock PH, at least sterilized properly. Try mo lang mabago ang approach, like when she cries for feeding kahit sobrang busog, try the pacifier first to soothe, tapos kung talaga pang hungry after a bit then feed na; pero sobrang importante talaga na i-confirm mo with your doctor kung normal lang ba talaga yung excessive feeding desire niya or may underlying issue. Hang in there, momsh, first month is the hardest, pero dadali rin!
