Ashley Graham "can't remember what life was like" before motherhood.
The 33-year-old model - who has 12-month-old Isaac with husband Justin Ervin - has taken to social media to reflect on her first year of motherhood, admitting it's changed her life in dramatic fashion.
Ashley wrote on Instagram: "Happy first birthday Isaac! ... I can't believe I'm already writing this, because it feels like just yesterday that we met.
"But at the same time, I also can't remember what life was like without you. Watching you grow and learn has been the greatest gift. (sic)"
Ashley also voiced her admiration for other first-time mothers who are facing the challenge amid the coronavirus pandemic.
The brunette beauty - who has been married to Justin since 2010 - wrote: "This year has taught us just how strong, adaptable, and fierce we can be. Sending love to everyone going through any stage of their motherhood journey during a pandemic!"
And after overcoming a challenging first year, Ashley is excited to see what the future has in store.
She said: "One year down and I can't wait to see where the rest takes us."
Meanwhile, Ashley previously admitted she felt like "an alien" was taking over her body during her pregnancy.
The curvaceous star revealed it took her some time to come to terms with the changes her body was going through.
Asked whether she found it hard to cope with the changes, Ashley said: "That was the wildest part. I thought, 'What about the things I've told myself? What about the affirmations I've gone through?' None of these mattered because my body was changing so rapidly.
"It really took me some time to figure it out mentally, because it was like there was an alien taking over my body."
