Following is a response from DHS staff member, Tom Pullum:
You have to use hv112 and hv114 to match children with their mothers and fathers. You can't do it with hv101.
Below I will paste a Stata program to do this. I don't use R but hope you can convert to R. It could be more efficient but it runs very quickly. This constructs a new file, with the variables renamed to have suffix "child", "mother" and "father". The cases are children age 0-17. The education variables are hv106-hv109 and hv121-hv124. A 2x2 table is produced describing the matches. Hope this helps.
