The expecting parents officially moved out of their Kensington Palace apartment earlier this month amid continued reports of a rift between Princes Harry and William. Coupled with the mounting public scrutiny around Meghan's pregnancy and reported feud with Kate Middleton.
As for Ragland's arrival, The Sun's source adds, "She wants to spend as much time as possible with her first grandchild and has come over for a sustained period of time. Meghan also wanted to show off her new house to her mum and the two have been enjoying spending time together."
