Ay, 3.5 na, perfect time na talaga momsh! A few of us tried going cold turkey with the sippy cup, pero honestly ang better approach is slow lang, let her pick her own cute cup, practice during snack time when she's relaxed, at gradually replace one bottle feeding at a time (usually lunch or merienda first, then ang bedtime bottle is often the last to go). Patience talaga, kasi some kids take weeks, iba umabot ng months, pero eventually lalabas yan, just stay consistent at celebrate small wins kasi nakaka-motivate sya!
