Following is a response from Senior DHS Specialist, Trevor Croft:
The variables v409-v414w in the women's data (the IR file) refer to the youngest child under 2 living with the mother. When the KR file is constructed, with one record for each child born in the last 5 years, those variables (along with other v variables in the IR file) are copied onto the records for all children born in the last 5 years, even when the variables do not apply to that child. Thus you must either use the IR file, or use the KR file after selecting just the youngest child under 2 living with the mother.
To correctly analyze the variables with the KR file, follow the selection documented in the Code Share Library:
Go to https://github.com/DHSProgram/DHS-Indicators-Stata; Select Chapt11_NT
*Selection of the youngest child under 2 years living with the mother is done with lines 96-100 in INTmain.do:
* Selecting for youngest child under 24 months and living with mother
keep if age < 24 & b9 == 0
* if caseid is the same as the prior case, then not the last born
keep if _n == 1 | caseid != caseid[_n-1]
