Though described as a "brave livlylike boy", Gloucester became ill with convulsions when he was three weeks old, so his mother moved him into Craven House, Kensington, hoping that the air from the surrounding gravel pits would have a beneficial effect on his health. His convulsions were possibly symptomatic of meningitis, likely contracted at birth and which resulted in hydrocephalus. As was usual among royalty, Gloucester was placed in the care of a governess, Lady Fitzhardinge, and was suckled by a wet nurse, Mrs. Pack, rather than his mother. As part of his treatment, Gloucester was driven outside every day in a small open carriage, pulled by Shetland ponies, to maximise his exposure to the air of the gravel pits. When the effectiveness of this treatment exceeded their expectations, Princess Anne and her husband acquired a permanent residence in the area, Campden House, a Jacobean mansion, in 1690. It was here that Gloucester befriended Welsh body-servant Jenkin Lewis, whose memoir of his master is an important source for historians.
