Weight growth trajectory: (a) Weight growth curve by gender. Solid line implies boy curve and dashed line implies girls. (b) Child growth curve by feeding mode. The solid line implies exclusive breast fed infants’ curve and dashed line implies mixed milks. (c) Weight growth curve by birth status. Solid line implies full-term infants and dashed line implies pre-term. (d) Weight growth curve by child rank in family. Solid line, dotted line and dashed line imply first, second and third and upper rank respectively
