Also reminder po na ang pagiging mataba ay hindi batayan ng pagiging healthy ni baby (for adults, it's even considered as unhealthy). As long as hindi sya sakitin, hitting milestones at within normal po ang height/ weight nya, then you shouldn't worry. Genetics is also a factor kung bakit pwede mas maliit si baby compared to others. Lastly, unlike formula milk, walang unnecessary sugar ang bm kaya no extra fats rin ☺️
