Ay, alam ko yan na worry na! Sa ganitong edad, normal talaga na may ilang days na walang tae, lalo na kung breastfed ang baby mo, kasi ang breast milk nila napaka-efficient na ginagamit ng katawan. One of my mum friends's baby naman, three days na walang tae tas biglang dumami, haha! But just to be safe, best to mention it sa doctor mo during the next check-up, especially if ang baby mo may feeding issues or seems uncomfortable, para ma-confirm lang na lahat ay okay.
