Olivia Bowen felt she would be "so rubbish as a mum" and never thought she would breastfeed before the birth of her son Abel.
The Love Island star, 28, gave birth to her first child with husband Alex - who she met on the dating show - on June 10.
In a post on Instagram on Saturday, Olivia discussed her experience of becoming a mother as part of World Breast Feeding Week.
Alongside images of herself feeding her son, she wrote: "I never thought I would breastfeed.
"I think where I felt like I was not a maternal person whatsoever before Abel was born, I had serious doubts it would work for me & I also didn't even feel comfortable with the thought of it!
"I would go as far as to say it freaked me out a bit. You all know I wasn't sure on having kids & it's mainly because I felt like I would be so rubbish as a Mum, not a maternal bone in my body pre Abel.
"Fast forward to when Abel was born & he first latched in the hospital it couldn't of felt more natural. The bond & connection I feel with him when feeding I will be forever grateful for.
"It's not always easy, those first few weeks the emotions are no joke. I had a couple of days where he wouldn't latch properly & I felt like a complete failure, I felt like I was failing myself & failing him - even though I told myself before I wasn't bothered about breastfeeding.
"The first week I was squeezing my engorged boobs over the bath, I woke up with wet sheets from leaking & I constantly worried about how much he was getting & was it good enough?!
"I was convinced I would stop breastfeeding after a month, then told myself 3 months & now I'm saying 6! There is no feeling like it.
"When his little eyes look up at me & when he goes all sleepy & content. So close to you who am I!!!! I would never have imagined to be writing this."
The reality star said she has learnt to "trust the process" and is "grateful" for her ability to breastfeed.
Olivia and her husband met on the hit ITV2 dating show in 2016 and married in September 2018, making them one of the rare couples from the programme who have remained together.
