Pre-pregnancy body mass index (BMI); Gestational weight gain (GWG); Large-for-gestational age (LGA);

^*Normal weight BMI was used as the reference group. BMI and GWG from first and second pregnancies were used for first and second-born infant analyses, respectively. Analyses were adjusted for the following covariates: maternal ethnicity, education, and smoking during first pregnancy.
