@unitechrist Snuggles, bounce on a yoga ball, tummy time if they want, slow or bouncing dance parties while baby wearing (if your body is up for it), walk outside, read your favorite book out loud, sing, look at black and white pictures... but I put so much pressure on myself to entertain him, it's really ok at this stage to do as little as you want and just hang out together and rest.
When the baby is older and starts looking around, going to empty museums during the day is top notch.
