It‘s in the second volume, page 87 „I set out from Bayreuth“ to 102 in the English edition you linked in the master post. (Actually, Wilhelmine‘s and her husband’s visit goes on somewhat longer, but that‘s the relevant time space, until „we followed the King into the year 1733“, because yes, Christmas happened. As you‘ll be able to see, it was the usual insanity among Hohenzollern family interactions, with the only good thing being that Fritz and Wilhelmine had a loving reunion (as opposed to the tense one during her wedding) and could back each other up again.

(Incidentally, about the spelling of the Franconian principality - the 17th century French writing folk usually wrote „Baireuth“, or even „Baireut“ but it really was and is „Bayreuth“, hence my using that spelling consistently.)
