You're using the unweighted data. You'll have to weight the data to match what's in the report. Once you weight the data, you should be able to match the total number of children born in the two years preceding the survey (97,989). As mentioned earlier, the number of children in the second column of Table 10.4 is the denominator (the total number of children born in the two years preceding the survey). It is not the numerator (the number of children born in the two years preceding the survey who were ever breastfed).
