AITA for moving all my daughter’s belongings to my parents house and leaving nothing for my husband’s affair kid?

AITA for this? My husband told me Saturday that he’d had an affair and had a kid from it. Our kids are 14m and 10f and this child is 9f. Something happened to her mother in the last couple weeks (I was a little too busy screaming at him to listen to the details) and he was leaving to go get her. My daughter came to me crying saying that he told her she had to share her room and her stuff with this girl for now. I called my parents and they agreed to her staying in their guest room (2 bedroom condo so my son and I are staying at the house).

We packed her stuff and Monday my parents, sister, BIL, and nephews helped us move ALL her stuff to my parents place. They also helped put locks on my bedroom and my son’s bedroom. We moved all my husband’s stuff from my bedroom to the 4th bedroom that he used as a home office.

Yesterday evening my husband got home with his affair kid. He got mad about all the stuff being gone and nothing being left for her. She’s from a much warmer area and doesn’t have clothes for the cold here (we live in the northern part of the US). This morning he caught me in the kitchen to complain to me about it again and said I was beint cruel by not making my daughter share with her. AITA?
