The mum-of-three has been sharing pictures of her kids at Disneyland with Noel and Sue, as well as at their holiday home.
And Sue has also been posting on the family’s Instagram Stories, with many of the snaps of Millie’s kids.
Over the top of a picture of Millie’s son Chester asleep in his buggy, Sue wrote: “Disney got me like…”
Chester later perked up for a trip in the pool, in a photo shared by Millie’s partner Harley Passmore.
Sue also posed up with Millie’s baby daughter Elodie, with both wearing their sunglasses.

“Love this picture!” Sue added.
And another snap on Millie’s Stories showed her sister Sophie with her daughter Ophelia on her shoulders.
“Magic Kingdom!” Sophie wrote over the top of the picture.
Millie’s decision to join her parents and siblings in Florida comes almost a year to the day that a “feud” broke out between the 22-year-old and her parents.
It all started on April 4, 2023, when Millie took to her Instagram Story as she responded to a video Sue had shared, of her and Noel surprising some of their grandchildren with a holiday to Florida.
Millie left the post up for around an hour, after her mum, dad, and numerous siblings jetted off to the Sunshine State.
Over a screenshot of the video, Millie wrote: “Cute? But you’ve made money from all your grandchildren but choose your favourites.
“Said my piece.”
Continuing in the Instagram post, she said: “I recall my kids being in the whole 22 Kids And Counting – not a single sight viewing of the rest in there. Bare 1 ep.”
The issues between the family seemed to have come to an end by August last year, when Sue publicly wished Millie a happy birthday.
And things got so much better between mother and daughter that Sue also acted as one of Millie’s birth partners when she welcomed baby Elodie into the world in September.
And after Millie shared news of Elodie’s arrival in a post on Instagram, Sue was among the first to comment.
“Aww Millie she’s just so beautiful,” Sue wrote.
“I’m so proud of you you did amazing bringing her into the world
“Thank you so much for asking me to be with you. Love you Xxx”
Sue also posted a snap of herself holding the newborn on her family’s Instagram page, writing over the top: “Welcome to the family Elodie-Jade.
“So proud of you millie you did amazing – she’s a such a beautiful addition to the family. Congratulations.”
And new dad Harley also took to his Instagram page to share his joy after Elodie’s birth.
“Couldn’t be anymore proud of you with how amazing you did delivering our beautiful girl into the world I love use so much my family is now complete!” he wrote alongside the same pictures Millie had shared of the new arrival.
“Also thank you so much sue for helping millie get through it, also i wouldn’t of got through it without you.”
“Aww Harley she’s just adorable,” Sue replied.
“I’m so happy for you all, what a beautiful addition to the family.”
