Amira,
The _1, _2.... are in fact for different children - all children born within the last 3/5 years. From the recode manual (https://www.dhsprogram.com/pubs/pdf/DHSG4/Recode4DHS.pdf)
The maternity history contains up to six entries, relating to births in the three/five years preceding interview. The use of three/five years is country specific. The entries are in reverse order, such that the first entry relates to the last birth in the last three/five years. There is an entry for all children born in the last three/five years including all twins. The period of three/five years includes months 0 to 35/59 prior to the interview, with month 0 being the month of interview. If there are more than six births in the last three/five years then only the last six are included in the maternity history. Each of the following variables, duration of breastfeeding (M5), duration of postpartum amenorrhea (M7) and duration of postpartum abstinence (M9) may have several cases coded 97 "Inconsistent" since the duration of breastfeeding, amenorrhea or abstinence was impossible in the interval between the birth and the following birth or date of interview if the most recent birth (only the date of interview in the case of breastfeeding).
