hi hi all parents, would like to ask if anyone has such experience…?

my current flat is within 1 km of school and my parents new flat also within 1 km of sch…
I intend to move maybe this year or next year which makes my registered address beyond 1 km but within 2 km…
would it be a good idea that I change my registered address to my parents? if I move beyond 1 km but within 2 km… will my child be penalised?
