Kirstie Allsopp has slammed young couples who wait until their thirties to have children.

The Location, Location, Location presenter, 47, took to Twitter on Wednesday to urge women in their twenties not to wait until they 'have more money or feel ready', and to save their money for 'proper childcare', instead of splashing on lavish weddings and expensive houses.

Expressing her frustration at millennials who tell her they want 'a few more years of fun', she argued that 'nothing will ever be more fun than children'.

Kirstie also revealed her regret at waiting until she was 35 and 37 to have her sons Bay, 11, and Oscar, nine, admitting that she was 'too old' to have a third, and had only waited until her thirties to start a family as she hadn't met the right man.

However her impassioned Twitter thread sparked a heated debate, with many followers warning her that her message was putting unnecessary pressure on young couples, and could panic women into starting families.

Taking to Twitter, Kirstie joked that 'someone should probably take her phone' before writing: 'If you want kids, if you are in your late 20s and if you are in a solid relationship and if you can afford it have kids NOW.

She claimed: 'It does NOT get easier the later you leave it, buy a cheaper house, a bit further from the shops & restaurants and keep some money back for childcare.'

Arguing that young couples should spend less on weddings and hen dos and save the money for their children, she continued: 'Do not blow £20K on a wedding & spend two years planning it because when that baby arrives you will love it more than anything in the world.

'The money you spent on the dress/hen night/cars/posh hotel will be nothing compared to your longing to afford the best childcare you can.'

Branding children as the 'most fun you'll ever have', Kirstie continued: 'When I'm faced with a couple in their late twenties who 'want a few more years of fun' I want to say 'kids are fun, kids are the best fun, nothing will ever be more fun, non-one will ever make your laugh more, or fill your heart with such joy.'

Kirstie also revealed her regret at waiting until she was 35 and 37 to have her sons Bay, 11, and Oscar, nine, admitting that she was 'too old' to have a third, and had only starting a family it until her thirties as she hadn't met the right man. They are pictured in 2014

She added in capital letters: 'If you want them don't wait'.

And replying to a follower who branded her message 'dangerous and damaging', she hit back with: 'No it is not damaging, lying is damaging, the 'kids aren't fun, work is fun, booze is fun, fashion is fun but kids aren't fun' is what's damaging.'

Reflecting on her own family, Kirstie revealed the reason for her impassioned rant, admitting that she was 'in pieces' about her boys leaving prep school.

'In two weeks time both my boys leave the prep school I've been a step-parent & parent at since 2007.

'I'm in pieces about it. I can't believe they have grown so fast. I was nearly 35 & 37 when I had the boys, I never had a third, too old. But very lucky to have had the 2 I did,' she explained.

Revealing her own reasons for having children in her thirties, she concluded: 'I had kids late because I hadn't met anyone, this is the case for so many other women, but this isn't a reason not be truthful.

'Loads of people say to me 'we know...' but if everyone 'knows' how come I'm faced with so many couples who 'want more fun'?'.

Kirstie's thread quickly racked up hundreds of replies and retweets.

Slamming the TV presenter's message, one follower wrote: 'Stop telling women in their late 20s they’re running out of time to have kids. It’s so damaging.'

Another argued that millennials should be allowed to live their lives to the full while they were still commitment-free, so they wouldn't feel they missed out later.

'If you're in your late 20's and are financially stable and want kids, put it off for a year or two, take a few foreign holidays a year where you can scuba dive and back pack and do adventurous stuff because all that will be gone once you have kids (unless you have staff)', they tweeted.

Another told how her friends who had settled down young due to pressure were now divorcing, while she waited until later and was still happy.

She wrote: 'I totally understand what you are saying however putting pressure on twenty-somethings to have children is just counterproductive.

'Interestingly all of the people I know who had kids in their mid twenties are now divorced!! I had mine at 34 and 39, we are settled and happy!'

Elsewhere a mum in her forties said it was easier this time, than in her twenties, tweeting: 'I had two in my early twenties and tried relentlessly for a third.

'After 15 years and fertility treatment, I had a third and fourth at 38 and 41. I have two in university and one in nursery and school. I run my own business. I'd say being a Mum in my forties is far easier than it was in my twenties'.

Another added: 'I'm in my twenties. I intend to live life before I have children. It's nonsense that it gets harder to conceive the older you get. Your fertility is determined the moment your ovaries are formed. If it happens, it happens. If it doesn't, it doesn't. Reproduction is not validation.'

But some followers agreed with Kirstie, with one parent tweeting: 'I totally agree!

'Never going to be a right time and you will always want to have saved more/have a bigger house but health is the most important thing and the older you are the tougher it gets. I think people underestimate how hard pregnancy and infancy is'.

One wrote: 'If you have them when you're younger, when they're old enough to look after themselves a bit you're still young enough to get out and enjoy yourself - child free. Or we're starting to take our eldest two to gigs with us. I'll be 40 next year and my eldest will be 16'.

Some expressed their regret at their parents never meeting their children as they left starting a family until later in life

Kirstie's Twitter thread comes just days after she told the The Sunday Times that she doesn't intend to follow her family tradition of sending her children to boarding school, after her own experience of 'bullying' and 'low-level misery'.

The presenter said her sons Bay, 11, and Oscar, nine, will attend a London secondary day school, as she can't imagine sending them away until they're at least 16.

Kirstie, 48, was sent to boarding school at the age of eight, after her father attended Eton College, but expressed concerns about the 'weird' system.
