We saw the newborn Prince Louis leave hospital in his Britax car seat - the same one William and Kate chose for transporting Prince George and Princess Charlotte home - but since then the youngest member of the family has been out of the public eye.
That changes on 9th July, when the now 11-week-old Royal has his Christening service in the Chapel Royal at St James's Palace, conducted by the Archbishop of Canterbury. It is the first time that the Duke and Duchess of Cambridge and their three children will all have been seen together.
As well as the famous cream lace and white satin Christening gown, also worn by his older brother and sister, Prince Louis may well travel as Charlotte did for the occasion in the traditional Millson pram, previously used for their great-uncles Prince Andrew and Prince Edward.
William and Kate have already been spotted pushing their youngest child around Kensington Gardens in the elegant navy blue Balmoral classic pram from Silver Cross that Kate chose with a bit of help from her mum for baby George. The then-£1,600 model was provided with some additional accessories, specifically requested by loving grandmother and experienced mum-of-three Carole Middleton - including the insect net that Silver Cross has since made a standard feature in its range.
Silver Cross, known as the ‘Rolls Royce of prams', has a long history of providing luxury carriages for the smallest members of the Royal family, and received a Royal warrant in the early 20th Century. The Balmoral was renamed as such after the Queen herself used one at Balmoral Castle with both Prince Charles and Prince Andrew. Like many parents, however, the Duke and Duchess of Cambridge house a few different sets of wheels. Kate has also been seen pushing an £850 Silver Cross Sleepover in the past - another navy pram, but in a far less traditional, more practical everyday style than the Balmoral.
With the Royal family known for a love of the countryside, outdoor sports and equestrian events, it was no surprise that - once again guided by Kate's mum Carole - they turned to Out'n'About for a pushchair that would take them off-road with ease. They opted for bespoke navy blue - very much their colour of choice! - for the Nipper they ordered for Prince George, and the colour has subsequently been made available for the rest of us too.
Rumour has it that when family-run British company Out'n'About asked Kate and William if they would like another all-terrain stroller for Princess Charlotte, they
confirmed that there was nothing wrong with the first one!
Kate has famously recycled some of her favourite children's clothes, passing them down from George to Charlotte, as well as her own outfits, so we wouldn't bet against Prince Louis enjoying some great days out in the Nipper too! With the pushchair market continually changing, though, we'll certainly be watching out for his parent picking anything new this time. And of course Kate will no doubt be offering advice to her pregnant sister as well. Pippa's first baby - a first cousin for George, Charlotte and Louis - is due in the autumn.
