I’ve read articles that say kids get their intelligence from their mothers 😂
I agree with others that you can’t ‘make’ children intelligent but you can create a home life that encourages curiosity, creativity and knowledge.
my children are clever to varying degrees. We never got houses them or forced them to do loads of school work etc. however both me and DH are also not completely stupid so ther is probably an element of genetics at play.
We go however have a house of books, lots of board games, and eat dinner together with no electronics and talk- about all sorts, if we don’t know the answers to random questions we find out together. Holidays aren’t spent at all inclusives consisting of beach/pool/bar, we go to places with ruins and museums and things to do.
I’ve also read that kids who go camping and spend time in nature do better at school. We all do scouts and camps etc.
now all of the above could have made a difference or maybe the kids would be the same even if we never did anything with them.
my advice is to be led by your child - enable them when things genuinely interest them, provide them with opportunities without forcing it down their throats. Let them enjoy life praise effort more than attainment. My eldest gets As and As with little effort. DD who is in year 11 got her physics grade from a C to an A last term with some revision and extra effort. That to my is worth more praise than getting an A without really trying.
dont forget that social skills, practical skills and common sense along with kindness and compassion are also very valuable skills which may actually have more influence on how successful someone is later in life.
