Delayed Teething

Sino po tulad ko dito na 13 months na ang baby wala pa din ngipin, pero marami nakabakat sa gums? I know it's normal and for some babies up to 15-18months ang eruption ng first tooth or in most cases first set of teeth dahil sabay-sabay ang labas. EBF kami since birth and we started complementary feeding at 6 months, he started showing signs of teething at 5 months.
