East Coast Heat

So we are in New York and the heat here today is excruciating. My little human normally runs a little hot but today he just seems so miserable. We have the fan on (our AC broke down this morning 😩) and I have him in nothing but a diaper currently but he still seems miserable. Any tips on how to keep my heat sensitive bub happy? He's been nursing a bit more than usual which I'm assuming is him trying to keep hydrated. Any tips would be lovely! We have been inside all day also so no going out in this awful weather.
