"At the time my partner [Zellweger] was filming her new project and her covid diagnosis placed the whole production on pause," the documents stated.
Anstead also noted an alleged incident that happened earlier this month, in which he claimed Hudson was returned to him with an awful sunburn.
According to legal papers, the Flip or Flop star, 38, told her former husband — who insisted their little boy was "crying in pain"— to "give him Tylenol" while hopefully stating, "I'm sure it will be better tomorrow."
Anstead also went on to claim Haack only sees their son "9 full days each month" since Hudson was born and alleged she uses their son as a pawn for her social media accounts.
As OK! previously learned, on Thursday, April 28, it was reported the motor specialist had filed for full custody of their little boy after sharing joint legal and physical custody of the toddler with the Christina on the Coast personality following their September 2020 split.
“What Ant is doing deeply saddens me. If this was really about Hudson, as he says, this should have been handled privately with a private judge or mediation, as myself and my attorney have suggested,” Haack said in a statement to HollywoodLife.
“I have had my share of ups and downs but I am a good mom and I love my children with all my heart and I will always protect them," she continued.
However, mere hours after the news broke of the filing, an Orange County Superior Court judge denied Anstead's request for full custody citing he had "insufficient showing" of concerns surrounding Hudson and didn't provide Haack with enough notice of his request.
