Any Canadians know??

I am a Canadian citizen living in the US. I haven’t been home to see family because of my pregnancy and then covid hitting literally the month before our last planned trip 🤦‍♀️

I am vaccinated and it says I can travel without quarantine but all I can find is that unvaccinated children under 18 have to still quarantine. My baby is not yet 2 so he isn’t eligible for the vaccine. Would he have to quarantine?? This seems insane and illogical because if he’s quarantining and I am able to roam free wouldn’t I be spreading anything he might have?? Others would be with us so he wouldn’t ever be alone in quarantine it just seems silly to insist a baby quarantine when the people traveling with them don’t have to.
