Ay ganyan din nangyari sa akin nung si baby ko pa three years old, napilitan niya ko ng galit! Swelling at tenderness talaga ang una, pero usually lumalaki pa siya in the first few days kaya mahirap ma-distinguish if it's just trauma or actual lump. Suggest mo i-check ng doctor agad para ma-rule out any complications like milk duct blockage or infection, lalo na if may pus or fever na, kasi important na ma-monitor niyan especially while breastfeeding pa rin. In the meantime, ice compress and paracetamol can help with the pain, at continue feeding if kaya mo para hindi mag-clog ang ducts. Good luck, mama, these toddler moments are wild!
