In 1923, his aunt Louise wrote of him that hie was 'quite too adorable for words, a perfect pet, so grown up & speaks quite a lot & uses grand phrases. He is the sturdiest little boy I have ever seen & I can't say he is spoilt.' p. 48
The book also remarks on early holidays spent at Panker, the Landgrave of Hesse's summer house on the Baltic coast. The Landgravine was Philip's Aunt Sophie's sister Margaret (nee Prussia) and a 'collection of royal cousins' would gather there. The Landgravine's son Christoph would eventually marry Philip's sister Sophie. About an hour away from Panker, was the estate of Hemmelmark (home of Philip's great-aunt Irene and her husband Henry of Prussia) 'where Philip jumped off a hay wagon and broke a front tooth.' (p.50)
Another visiting place was Cotroceni Palace where his cousin Helen of Romania (nee Greece) lived.
p.51: 'Philip goes to Adsdean [home of Louis & Edwina Mountbatten]' wrote Victoria Milford-Haven to Nona Kerr in June 1926, 'where they can keep him until autumn if desired, only for Goodwood week his room will be needed for guests, so if you (Nona) would still like & could have him & Roose [his nanny] that would be the time for his visit to you.' Philip went regularly to Nona Kerr over the years and he took to calling her 'Mrs Good...because she is good and that is the right name.'
