Ay, don't worry mama, one time lang yan! Toddler milk is basically just a bit more concentrated and may have different nutrients, but it's not toxic or anything, a lot of us have had that scare din talaga. I'd say observe her for the next day or two para sa any tummy upset like constipation or weird poops, but honestly most babies are fine with one accidental sip. If you're still worried or she starts acting off, mas safe na tawagan lang ang pedia para sa peace of mind, okay?
