Hi momsh! Normal lang yan, walang dahilan mag-alala, some babies start teething as early as 3-4 months, pero iba naman ang iba, kaya pwede ding 12-18 months pa lang mag-start, especially if may family history ng late teething. A few of us moms in our circle had the same situation kaya yan talaga ang nag-comfort sa amin. That said, best to mention it sa pedia during the next checkup para ma-assess lang nila properly at ma-rule out kung may other concerns. Sabi ng isa sa mum friends ko, ang importante lang talaga ay may development naman sa ibang areas (motor, social, cognitive) kaya alam mo na healthy ang baby overall.
