In a series of clips, which Laura-Ann posted in the highlights section of her Instagram, Middleton can be seen talking to the blogger's 2-year-old son, George.

"Hi George, what a cool name you've got, and you look very smart in your bow tie," the duchess says in one video.

After that, Middleton asks how old Laura-Ann's other son is, but the video cuts off because the blogger's mom's phone died. However, according to the mother of two, after she said her older son is aged 4, the duchess said, "Oh, he's the same age as Lottie" - an apparent reference to Princess Charlotte, who turns 4 in May.

As seen in photos published in The Sun, Middleton bought art supplies, pictures, and children's books from the store.
