Hi, thanks for writing in . i understand your concern. it is very much normal to add on around 11kgs of weight in the nine months of pregnancy. about the second baby you want as a normal , it depends on your pelvic fetal index. firstly it is important if your first child was born through emergency or elective c section. if in this delivery there are no indications like pelvic disproportion or any other indications that compel your obstetrician to select elective c section, there is something known as trial of labour where they try to deliver baby through normal vaginal delivery. trial of labour is done provided in your first delivery lower segment c section was done . in classical c section it is never taken up for trial of labour due to risks. However, it is considered safer to conduct the second delivery through c section. Since you have not mentioned the spacing between the two children i would advice you to kindly consult your doctor regarding this.
