My wife and I share a bathroom with our 2 year old son. His bedroom is on one side and ours is on the other. We'd like to reduce the amount of noise coming from our bathroom so we don't wake him when we shower.
I have already replaced the doors with solid core soundproofing doors. But I'm trying to figure out the best way to further seal off the doors. There is still light and air leaking through the frame of the doors when they're closed, and along the bottom, which means sound is probably transmitting too.
Is there a good style of weatherstripping that would help? Stick on felt? Compression weatherstripping?
Would an automatic door bottom be worth the effort or would a simple door sweep suffice?

Rubber air seals along the bottom will be your best bet. An automatic bottom seal may work slightly better, but its a very slight difference over a properly installed gasket seal.
Make sure your door is perfectly balanced in the frame before installing a gasket. You need to make sure the gap is uniform across the entire bottom of the door.
Foam tape would work just as well across the top and sides, and may be cheaper depending on what bottom seal you choose.
Its worth mentioning, unless you have an inch or more gap, its unlikely this extra gap-seal is going to solve the underlying issue. So much of the sound is still going to be transmitted through what are most likely uninsulated interior walls. Soundproofing tends to be a project that just keeps going.
