In NFHS 5, within the Women Questionnaire Module, section 499M pertains to querying respondents about the liquids or foods consumed by their child, as indicated in section 499L, during the preceding day or night. This inquiry extends to instances where the mentioned item was consumed alongside other foods.
This section is specifically administered if the child is under 2 years old and if the mother has at least one child born in 2017 or later who resides with her.
However, I've observed data related to questions 499M-A to 499M-A for children older than 2 years in the children recode data file. This raises the question of why this data is present, given the stipulated age criterion.
Please explain

Here's an additional response from Senior DHS Staff member, Tom Pullum:
There are many parts of the questionnaire in which decisions about cutoffs and eligibility must be applied during data processing, that is, during the construction of the indicator. You have to discard those extra cases by coding the indicator as "NA" (a dot in Stata) for them. I would expect that the cases you have identified are very close to the boundary for 2 years of age.
Sometimes the questionnaire is intentionally designed to bring in more cases than necessary, in order to avoid leaving it to the fieldworkers to make crucial decisions about eligibility. DHS tries to balance that concern against minimizing the amount of data that will have to be discarded.
Yes, I see that for v413 (for example), most (about 70%) of the responses are for age<2 years but about 30% are for age 2 to 4. There is probably a reason why there are so many responses for children aged 2-4 but I cannot take the time to go down that rabbit hole. I hope another user can help with your question.

I've observed a noteworthy volume of records extending from 24 months up to 59 months of age for a specific variable in my sample (- v409- indicating whether a child was given plain water). Below, you'll find the tabulated results generated from Stata. Within the age bracket of 24 to 59 months, there are 35,672 records available, which signifies a substantial quantity. This prompts the question: given that the survey was conducted using an online CATI method where skip logic should have been applied for subsequent questions, how did so many entries manage to be recorded?
