The question on low birth weight and mother's perception of their child's size at birth are mutually exclusive. The question on mothers perception is asked before the birth weight, please see the attached file showing the related questions. Interviewers are instructed to not change QRE 430 once Q432 is filled. For example, if the child's birth weight was < 2.5 Kgs and mother had responded that the child was very large, that's what will be recorded and included in the data file.
