She welcomed her first child with husband Hugo Taylor in May.

And Millie Mackintosh got emotional over her baby daughter Sienna ‘growing up so fast’ in a candid Instagram post on Thursday.

The former Made In Chelsea star, 31, admitted that her ‘heart sinks with sadness a little’ as Sienna gains independence and needs her less.

Millie said that with Sienna now aged seven-and-a-half months, she is constantly ‘moving, learning and interacting’. 

The reality star said that she feels conflicted over the developments as it is ‘such a joy’ but also ‘tinged with a little sadness’.

Posting a sweet picture of herself and Sienna, Millie penned: ‘Sienna is 7 and a half months old now and as any parent knows, it’s a beautiful yet complicated age. She’s is so keen to be busy! 

‘She is constantly moving, learning and interacting, she is already trying to stand up and I can see her yearning to be more mobile, I think she’ll be crawling any day now! 

‘I’ve been feeling a bit conflicted emotionally, because every time she reaches a new milestone, I burst with pride and then my heart sinks with sadness a little as she gains her independence. 

‘When I hold her close for a cuddle she pushes away and just wants to climb on me and explore, she won’t stay still for a second unless she’s asleep.  

‘Her routine (which is a life saver) also means she doesn’t nap on me anymore and the only time I feel I get to hold her in my arms is when I’m giving her a bottle (which she finishes in 5 minutes.)’

Millie then reflected on how fast Sienna is growing up, she continued: ‘My little baby is growing up so fast! It feels like only a week ago all her 6-9-month clothes were too big and suddenly they’re all a bit too snug! 

‘She now faces out in the buggy on our walks, her mind is like a sponge absorbing everything she sees and interacts with, but I miss looking at her little face.’

Millie added that she isn’t ‘complaining’ about Sienna’s developments and although she is loving seeing her daughter grow in confidence, she does feel ‘a little sadness’ as she needs her less. 

She said: ‘I’m not complaining at all, I love seeing her take leaps in her development each week, it’s such a joy but it’s also tinged with a little sadness each day she needs me less. 

‘I’m learning to cherish the little moments each day, and I sway between wanting her to stay tiny forever, to getting excited about all the things she’ll eventually go on to do in life.’

Millie sweetly concluded her post with: ‘One things for certain, you never stop being someone’s child, so in some ways she’ll always be my baby.’

Last month, Millie reflected on her first six months of motherhood in a candid interview. 

The TV personality spoke to Mother And Baby about the affect ‘mum police’ trolls have had on her self esteem as well as her changing relationship with her body. 

‘There are definitely some mum police out there that really will like jump on you and criticise anything you do. You can’t please everybody,’ she explained. 

‘I really just try and take a deep breath, put my phone down or go for a walk if it’s really got to me but I think you just have to rise above it.’ 

But the star admitted she’s found huge positives in social media in her role as a mum, especially when she shared her family’s experience when Sienna was diagnosed with Hip Dysplasia at three-months-old. 

Sienna had to spend six weeks in a brace and will continue to have weekly appointments and scans every six months until she is three-years-old. 

Millie said she grew emotional when her followers shared their own experiences of the condition with her and it helped her through.

She has also received an outpouring of support after sharing her honest relationship with her post-birth body, admitting she is a stone heavier than when she got pregnant, but she is feeling confident six months after the birth.  

‘I think a lot of my identity has always been in how I look and how I feel in my body and having it change beyond recognition – it was a shock,’ she said.  

‘I found it particularly hard after I’d had the baby and actually adjusting took a while. It was hard not to be critical of myself, even though I knew my body created a life.’ 

She added now ‘I love looking at pictures of when I was pregnant and just being like, wow, like my stomach was huge! And just knowing that Sienna was in there. And I’m so in awe of my body now I definitely have a lot more respect for it. And yeah, it does look different!’
