The duchess did not make a public appearance on St. Patrick's Day 2016, opting to remain at her and William's Anmer Hall residence in Norfolk with George and Charlotte, ahead of state visits to India and Bhutan. William, who bears the title of Colonel of the Regiment of the Irish Guards, attended the annual parade without her and presented sprigs of Shamrock to the officers and guardsman by himself.

Kate is due to give birth to her and William's third child in April.
