government pension HRP

marie_hc

hello forum 
I am short on my pension, after talking to NIC & pensions people I was told I could claim for my youngest child til she was 19 because she was in approved education.

So I wrote tos NIC for the missing 3 years  I am using HRP  ( home responsibility protection )  for parent who reared children and did not work. 
they have now told me I have given 22 years the max  
when I asked is this was per child or all three silence then he said overall !!!

Does anyone know anything about this HRP I did look as he said on gov uk but it is basic and doesn't go into detail 

TIA
