1, There are typos in Table 1. 
2, It will be better if can adjust the information of sample mothers, for example, education, medical
insurance and first birth.
3, Why still focus on information about lean, overweight and Obseity in the analysis as there is no BMI
information fro sample mothers? 
Need 
more evidence to support the maternal weight range of >38 - 65.6
kg and weight range of ≥85.0 - 186.0 kg group in the analysis.
