Keeping baby awake during the day

Hi Ladies,

Any tips on keeping my 6 weeks old baby awake during the day? He naps the entire day, wakes up to feed and falls asleep on the breast. He’s up from 11ish- 6am every night.

I open all windows for light, have the tv on and I allow my 2 year old to be her usual playful, loud and talkative self during the day but he stays asleep in all the noise. I can’t sleep while he sleeps during the day because I have a 2 year old to take care of.

Help please...mama needs some sleep.
