Dear Bridgette,
Thank you so much for your kind help. I tried to replace the variable for age using the syntax you gave me. However, the age seems not to match with that of the report. For instance, the total sample for children aged 0-5 months who practiced exclusive breastfeeding is 1715; for 9-11 months it is 888. Kindly enlighten me on where I might have gone wrong. Below is the SYNTAX that I used to create the age variable and breastfeeding practices (early initiation of breastfeeding, exclusive breastfeeding, predominant breastfeeding and bottle feeding:

gen age=b19

keep if age<24

. keep if bidx==1

ta age [iw=v005/1000000]

. gen water=0

.
. gen liquids=0

.
. gen milk=0

.
. gen solids=0

.
. gen breast=0

.
. gen bottle=0

. replace water=1 if (v409>=1 & v409<=7)

. replace liquids=1 if v409a>=1 & v409a<=7

.
. replace liquids=1 if v410>=1 & v410<=7

.
. replace liquids=1 if v410>=1 & v410<=7

. replace liquids=1 if v410a>=1 & v410a<=7

. replace liquids=1 if v413>=1 & v413<=7

. replace liquids=1 if v413a>=1 & v413a<=7

. replace liquids=1 if v413b>=1 & v413b<=7

. replace liquids=1 if v413c>=1 & v413c<=7

. replace liquids=1 if v413d>=1 & v413d<=7

. capture replace liquids=1 if v412c>=1 & v412c<=7

. replace milk=1 if v411>=1 & v411<=7

.
. replace milk=1 if v411a>=1 & v411a<=7

.
. replace milk=1 if v412>=1 & v412<=7

.
