My wife is constantly pushing my kids towards the sciences (SPACE / PHYSICS?

My wife who has a phd in astrophysics but is on maternity leave for our youngest (3 months) is constantly pushing out 4 year old.

everything she does with him is teaching him mathematics, the planets, solar systems, all about the universe and so on…since they are both at home it’s at least 5-6 hours a day of teaching him these things.

everything he has is space related, his room, his toys, his clothes, you name it

he seems to love it and not get bored but I’m worried she's pushing him too hard

he already knows his multiplication, division and is starting on fractions and so on so he is definitely above average in intelligence

what do i do
