Kate Middleton reportedly wants a fourth child for a very special reason

Kate Middleton is said to have plans to have a fourth baby, and the reason behind it is so sweet!

The mum-of-three welcomed her youngest child, Prince Louis, last year, but royal fans are already convinced Kate and Wills will want at least another baby to complete their brood.

Royal fans have been betting on Kate and William having a fourth baby aover the past few months, which suggests a lot of people think another little Cambridge is on the way.

And while it’s unlikely Kate is already pregnant – as she’s suffered from hyperemesis gravidarum during her previous three pregnancies, which would likely force her to cancel her royal engagements – reports suggest she does want another baby and for a very special reason.

As George and Charlotte have become a little duo, she wants Louis to have the same relationship with another sibling.

A source told New Idea: ‘Kate has seen the bond between George and Charlotte and thinks it would be lovely if Louis had a sister closer to his age.

‘Kate is doing things her way but William has always supported her and will do anything to make her happy; that is a promise he made before they married.’

Another reason why Kate is said to want more babies is because she reportedly prefers family life to royal duties.

The source added: ‘The simple truth is that Kate loves being at home looking after her kids.

‘She likes being a royal and meeting the public, but she wants to put off heavy royal duties for as long as possible and being a mum gives her the perfect get-out.

‘It may seem a bit selfish, but Kate feels the most important thing is to have a happy marriage and support her husband.

‘She looks at what happened to Princess Diana and Fergie and she wants to make sure she provides a firm foundation and family life for her husband and children.’
