Archie, the son of former royals Harry and Meghan, is reportedly loving life in the US.
The couple, who quit the royal family earlier this year, are based in California.
And their tot, now aged one, is said to be lapping it up, The Mirror reports.
Royal expert Katie Nicholl told Entertainment tonight : "I think he (Archie) is just about walking.
"He's a very happy little boy, he's loving life in LA.
Harry, 35, and Meghan, 38, are said to be "grateful" for the time they're getting to spend with their young son.
Ms Nicholl said that they will remain at their current address while they look for their "forever home".
Harry and Meghan came under fire after spending millions refurbishing Frogmore Cottage in the UK so they could move in.
This week bombshell court papers revealed Meghan felt "unprotected by the Institution (the royal family), and prohibited from defending herself."
She is currently taking legal action against her dad Thomas after a letter she sent was published in the Mail on Sunday.
The couple, who quit the royal family earlier this year, say they want to concentrate on new ventures going forward, focusing on eco tourism project Travalyst, which launched last year.
They have reportedly filed paperwork for their Sussex Royal charity to be officially dissolved, with trustees set to step down.
