Ay, possible pa talaga, lalo na kung 4 months pa lang si baby! A few of us moms actually got our supply back by going back to frequent feeding or pumping, one friend of mine relactated after almost two months of stopping, so hindi pa lost cause mo. The key is consistent stimulation lang, either direct latching or pumping every 2-3 hours, kaya if gusto mo talaga subukan ulit, give it a shot pero seryoso ang commitment kailangan. Best to chat with your OB or a lactation consultant about this though, para sure na healthy lahat at ma-guide ka properly on how to restart, they can check kung ano talaga nangyari at best approach para sa situation mo.
