 [ Symptoms ] can breast get bigger from working with infants if you are not nor have you ever been pregnant  i am wondering if it is at all possible for my breast to become bigger just by working with infants  holding feeding changing etc i have not gained weight elsewhere & i had my period 2 weeks ago the only change in my routine is working with infants i have read online forums some stating it is indeed possible but then others saying that it is ridiculous anyone that can help give me a little insight i would be very appreciative [ Disease ] most helpful answer i do not believe there is any scientific evidence that working with infants will cause breast enlargement i hope not since i take care of our one year old grand daughter twice a week if this assumption was true would not women in the child care industry all over the world have experienced this and be clamoring for a job there is likely another explanation for your breast enlargement
