The short answer is yes, though the early chapters were rewritten so many times that it's difficult to disentangle them. And keep in mind that all of this is only a
selection of the extant material -- Christopher tried to limit himself to documenting drafts marking major developments.
One of the important early critics was
the young Rayner Unwin, son of
Tolkien's publisher, who thought the early drafts contained too much "hobbit-talk". Tolkien replied, in Letter 28, that
"It agrees strikingly with Mr. Lewis', which is therefore confirmed. I must plainly
bow to my two chief (and most well-disposed) critics. The trouble is that 'hobbit-talk' amuses me privately (and to a certain extent my boy Christopher) more than adventures; but I must curb this severely".
You'll find an example of Christopher's influence in the Farmer Maggot episode, in which Tolkien kept trying to accommodate his son's desire to see
Frodo getting "revenge" for his youthful beating, despite the way the story was "supposed" to go.
One extended example of "hobbit-talk" was to appear, in the exchange concerning
pipe weed, between
Merry and
Theoden at
Isengard, where it would have had the characteristics of Menippean satire, but Tolkien removed it to the Prologue.
Fortunately, he left in the important Menippean satire at the Green
Dragon in Chapter Two.
