The Love Island star – who welcomed her first child with Tommy Fury in January – said her little girl will only take a bottle from her and refuses to feed with her dad.
Molly, 23, said: “We really need her to get out of the habit of only liking to have her bottles with me – because that’s not going to work.”
She told fans on her latest YouTube video: “Bambi has got into the habit of not liking to take bottles from Tommy, she just gets really really fussy with him.
“We’ve been trying to figure it out, it literally could be anything.
“It could be the fact maybe I breastfed her and I do a lot of the bottles with her, so maybe she’s kind of used to me doing it and kind of associates me with feeding time, obviously because we did start as a breastfeeding journey.
“This is not me being stereotypical of sexist in anyway but when your that babies mum, you do have a bit of a different…how do I explain it, it’s a mother’s touch sometimes and she associates me with feeding time because we breastfed.
“Tommy and I have said that from now he’s going to do her bottles, a lot more bottles, because we really need her to get out of the habit of only liking to have her bottles with me, because that’s not going to work.
“Today was ridiculous, we can’t do that again.
“Say for example if I go away, he wants to be able to have her by himself.
This comes after Molly was on the receiving end of hurtful comments about her body after giving birth to baby Bambi five months ago.
She posed in a cute red and white striped bikini top under the same linen top and trousers.
And while most people were full of praise for how amazing Molly looked, others weren’t so nice.
One commented: “Would have been a cute opportunity to show off real women’s bodies – stretch marks and all.”
Recently she told how she felt “zombified” juggling her baby with work before mum-shaming fans accused of her of leaving them “uneasy” with her conduct.
The former Love Island star has offered a glimmer of hope for her fellow new mums who may be feeling overwhelmed.
She wrote: “Being a mum consists of great days, bad days, normal days, overwhelming days, perfect days, sad days… a lot of days of just making it to the end of the day! But through it all, a crazy amount of love.
“To my new mums out there who are reading this… when people say ‘it gets easier’ it really isn’t just a passing comment. You’ve got this.”
