Oh man the 2's

Anyone else's 2 year old scream bloody murder when their partner wants to do something solo with the 2 year old?

The last week or so our 2 year old son has a complete fit when my husband wants to do anything that doesn't also involve me. I work from home and have our son home all day. My husband is a teacher and works mon-fri, but also has other activities 4 days a week that keep him at school or tutoring from home until around 6 or 7. Hes not 100% always present when he's home, on his phone or training for the marathon he wants to run. He deserves decompression time the same as all of us so im not knocking that at all.

Today it was nap time. Our son is starting to give up his nap, we are at about a 50% nap rate...3 or 4 days a week he will nap and the rest of the week he won't. He didn't nap until about 2pm and my husband got home at 330 to me and my son in bed because he wouldn't nap without me there. First he says we should wake him up to which I disagree so he says okay and just changes. Then our son starts waking up and my husband wants to switch spots with me so I can finish work. I was admittedly behind today because of a Dr appointment this morning and our son just starts bawling uncontrollably saying no daddy no daddy mommy nap with me. So I try to say it's okay daddy is a good guy he lives you etc etc, but nothing will help console him. I finally say okay it's okay daddy doesn't have to, and my husband gets upset and storms off saying I constantly undermine him solving our sons problems.

I dont know that I responded wrongly to this but I do understand how my husband is feeling I just dont know how to not cause undue distress to our son and not insult my husband at the same time.
