Oo, normal lang yan! A few of us mums noticed our kids still getting baguhan even at 3-4 years old, kaya hindi ka mag-alala. Usually it's just a phase and nagsisimula nang lumabas ang permanent teeth, so excited lang ang gums nila kahit wala pang actual teething happening. Check lang with your pedia if it seems painful or affecting eating, pero mostly ito ay natural part ng development at mag-ease na eventually.
