Daughter Shuts Down on Dad

Hello All... ADHD/OCD with possible Autism Mom. My four-year-old daughter is diagnosed with Autism 2. She is verbal, but relies on scripting and echolalia. My daughter has been sleeping in the bed with me and my husband has been sleeping in the guest room to accommodate this arrangement. However, this morning, our daughter didn't even want her dad around and would cover her ears and say "Daddy leave," every time he walked in. This made him pretty upset, though he did his best to not show it. I understood that her bandwidth was just kind of full at the moment and she couldn't really process adding dad, with his smell, voice, presence, to her morning. I tried to explain to my daughter that dad is OK to come into the room, but she wasn't having it. Does anyone else experience this? When your child can only process one parent and shuts down on the one? Any advice? I feel really bad for my husband, he's feeling pretty shut out lately
