Entertaining a newborn

My LO is 5 weeks old and spends more time awake. Before he would basically just eat and sleep but now he is awake for hours a day in between naps. I feel bad because I don’t know how to entertain him. I try showing him his reflection or placing him by lights to look at but I feel like he’s bored a lot of the time. I don’t have the energy to read/sing/talk to him all day (I try to do these things too but obviously after taking care of him adding entertainment to the mix is a bit exhausting) what should I do to entertain him but not wear myself out? I wish I had all the energy in the world to play with him and bounce him or read but by the time I’m done changing him, cleaning the house, feeding him, putting him to sleep, etc I need a break but of course that’s when he’s awake and bored. Help? How do you entertain a newborn?!
