Kate Chastain is revealing whether her first few months of motherhood have been smooth sailing or rough waters.

Nearly three months after the Below Deck alum welcomed her first child, a son named Sullivan Cay, she shared an update on how she’s faring as a single parent.

“I thought after being a chief stew on yachts I was like, ‘Oh, being a mom, how hard could it be?'” Kate exclusively told E! News on July 26. “It is so much harder than being a chief stew on yachts. It really is, but I love it.”

Though the 40-year-old previously said she was looking forward to raising Sullivan solo, she admitted she has been caught off guard by a few aspects of having a newborn.

“I guess what really surprises me is it’s not just feeding and diapers,” she shared, adding, “also the number of diapers surprised me. At my baby shower I asked my cousin, ‘So, how many diapers a day, like 3, 5?’ She’s like, ‘Oh no, no, no, no, no.'”
