Kensington Palace released four beautiful photographs ahead of Princess Charlotte's birthday tomorrow. The Duchess took the photos at the family's country home, Anmer Hall, in Norfolk in April. It's becoming something of a tradition for Kate to take photos of her children; as a keen photographer she always captures excellent shots and they offer a relaxed feel each time as George and Charlotte are so very much at ease with her. Below, Charlotte is looking at mum as she takes her photo. :) My favourite photo from the set is the one below showing a smiling Charlotte pushing her walker across the lawn. It's a delightful 'family album' photo and she looks simply adorable with a pink bow in her hair. It also looks like Lupo was eager to get in on the action, making the background of the photo. The Palace said: "The Duke and Duchess are happy to be able to share these family moments, ahead of their daughter's first birthday. We hope that everyone enjoys these lovely photos as much as we do." What do you think of the photos? I thoroughly enjoyed seeing them and thanks to the selection of four we were afforded the opportunity to get a glimpse into Charlotte's personality. She's changed so much in the last few months and appears to be having a splendid time exploring around Anmer. And...how cute are those expressions? HRH The Duchess of Cambridge Charlotte's pretty blue dress is also from Spanish brand M & H. It is from their FW15 Collection (below we see it in pink). It was worn with the Princess Charlotte Cashmere Rose Stitch Cardigan by Olivier Baby and Kids. The wonderful team at Prince George Pieces have been busy identifying Charlotte's outfits. The Princess wore her pink M & H cardigan, and Amaia Kids tights from the Queen's birthday portrait. Charlotte's navy shoes are the Early Days Emma Pre-Walkers. As for Charlotte's precious bows, it is thought they are also by Amaia Kids, retailing for £2.50. In one of the photos, Charlotte was holding the popular The Wheels on the Bus sound and action book. John Lewis As for her walker, it's the $145 Walker and Alphabet Blocks by Pintoy. Amazon Big brother George's first birthday portraits were taken at the 'Sensational Butterflies' exhibition at the Natural History Museum by press association photographer John Stillwell. The Prince was depicted toddling towards the camera with his arms in the air. Three photos were released in total - two with William and Kate included. It's hard to believe its been a year since Charlotte was born. Who will ever forget this day? Princess Charlotte Elizabeth Diana of Cambridge was born weighing 8 lbs 3 oz at 8.34 am. In June, photos of George and Charlotte taken by Kate at Anmer Hall were released. The Princess was baptised at St Mary Magdalene Church on the Sandringham estate in Norfolk on 5 July. A mother and daughter christening portrait by the one and only Mario Testino. The family of four. Photos released in November showed a smiling Charlotte playing with a toy at Anmer. Another precious smile for the Cambridges' Christmas card photo. The family enjoyed a ski holiday in March. It was the first time either George or Charlotte had played in the snow. And sitting on "Gan-Gan's" lap for the Queen's 90th birthday portrait. It's been a wonderful year, the Princess has grown so much. Wishing Princess Charlotte a very, very Happy Birthday! I have no doubt it will be an enormously special day for the family. :) If you're just joining us, yes, the Duchess is gracing the cover of Vogue; click here to find out more on that and enter to win a pair of Kate's Bow Gloves. Someday in the future Charlotte may even follow in her mother's footsteps and also feature on the cover. We'll see the Duchess on Wednesday - she has three engagements throughout the day.
