For Kate Middleton, Mother's Day 2016 will be an important occasion as the Duchess of Cambridge is a mother-of-two. Since her children, Prince George and Princess Charlotte are very young to plan something special for her, Prince William's wife may perhaps spend the day with her mother in Berkshire.

A palace source told Hello! Magazine that Middleton, 34, will spend the day privately. The publication speculated that she might travel to her hometown Berkshire and mark the special occasion with her mother, Carole Middleton.

Alternatively, the Duchess could spend the day at her home, Anmer Hall, in Norfolk with husband Prince William and their two children. No doubt, the day would be an eventful one because Prince George has been as a "little monkey" by the Duke of Cambridge, according to People.

The Magazine quoted Prince William, 33, as saying, "Charlotte is very easy, very sweet, but all the fathers say, 'Just you wait, when you get to 9, 10, 11, they go crazy."

The Hello! Magazine report claimed that the Duchess of Cambridge could release a slew of official portraits of her kids later this year. Middleton's daughter Princess Charlotte, who is ten months old, will turn one in May 2016.

"When Charlotte turns one in May, royal fans are hoping they will be treated to a new set of images, perhaps taken in advance by mum Kate, at a private celebration like Mother's Day," according to the report.

Mother's Day is celebrated on the fourth Sunday of Lent in the UK. The day, often called Mothering Sunday, bears no resemblance to the popular American festival.
