What would you do?

DH was working until 2am last night. He came to bed at 3.30am. At which time I was up with 1yo. Took me until 5.45am to settle DS, then I was up at 6.30am with DD. DH slept through all of this. So I've effectively been up since 3.30am.

I am working today at 12pm - 8pm. I am already shattered and dreading the day!

Should I wake DH at 9.30am to watch DS and I get a nap before work? Or suck it up and let him sleep?! He is working from home today and has no particular schedule. My Mum will be here at 1130 to watch DS so DH can work. DD is at nursery 845-330.

I'd let him sleep but then he is up with the kids tonight

If I wasn't working, I'd for sure let him sleep and I'd nap when DS naps after lunch but it's my work that's throwing a spanner in the works!
