Ay mama, I feel you, ang tagal talaga ng interval na yan! Honestly, this is something best discussed directly with your baby's pediatrician kasi alam nila ang exact vaccination schedule at kung may adjustment na kailangan based sa baby's age at health. A few of us moms had similar delays before, at ang doctors namin always assured us na okay pa rin, pero better confirm with yours para sure at walang worry ka. December is a bit far from October, so definitely ask the center or your pedia kung pwedeng mas mabilis or kung safe na ang ganitong interval, sila lang talaga ang makakapagsabi ng tama! Keep us posted okay, I'm rooting for your baby's vaccinations na matapos na agad.
