Chastain, who has not publicly identified her child’s father, previously opened up about her plans to parent on her own during an episode of Watch What Happens Live With Andy Cohen in January. “I’m doing it solo and perhaps with some help, but I’m happy to do it alone,” she said of her motherhood journey.

After her son’s arrival, Chastain praised the major milestones he had already reached.

“Sullivan’s 3 months now, so I think I’m finally finding a groove and I’m really enjoying it. I love it so much, but I am constantly shocked by how much work it is. And that’s coming from me, who was known on Below Deck for working quite a lot. It’s a lot of work that I love so much,” she exclusively told Us Weekly in August. “Postpartum was no big deal [for me] just because I was so distracted by having this baby. I’m very fortunate in that way and I’m just absolutely obsessed with him.”
