I love the name [name_m]Peter[/name_m]. I think it’s classic and friendly. I’m wondering what kind of fun pet names you think might come from [name_m]Peter[/name_m]? Besides the obvious [name_m]Pete[/name_m], which I think it pretty boring and kind of the opposite feel of [name_m]Peter[/name_m]. I don’t mind that it’s an eventual nickname, but I don’t want to call him [name_m]Pete[/name_m]. What do you guys think? Anything cute come to mind?
Other than [name_m]Pete[/name_m]/[name_m]Petey[/name_m] the only nickname I can think of would be intials from a middle
name like P.J. Or if you didn’t mind it being a stretch maybe [name_m]Rocky[/name_m]?
That takes a little bit of stretching but how about…
[name_f]Ettie[/name_f]/[name_m]Eddie[/name_m]
[name_u]Terry[/name_u]
That’s all I’ve got! [name_m]Peter[/name_m] really isn’t a nn kind of name.
[name_f]Do[/name_f] you know [name_m]Peter[/name_m] Rabbit, the books by [name_f]Beatrix[/name_f] [name_m]Potter[/name_m]? There’s a story I read, where there was a child called [name_m]Peter[/name_m], and he went by Rabbit a lot. I find it quite cute for a family pet name.
I like the suggestions of [name_m]Rocky[/name_m] and [name_u]Terry[/name_u]. [name_m]Perico[/name_m] is the pet name for [name_m]Pedro[/name_m] ([name_m]Peter[/name_m]) in spanish.
[name_u]Perry[/name_u], Pear, possibly [name_u]Pat[/name_u]?
[name_m]How[/name_m] about [name_f]Pet[/name_f]? 
I quite like the medieval [name_m]Perkin[/name_m]/Petkin.
Maybe Pep could work?
I don’t think [name_m]Rocky[/name_m] is that much of a stretch for [name_m]Peter[/name_m].
[name_u]Petya[/name_u] is the typical nickname for [name_m]Pyotr[/name_m], the Russian version of [name_m]Peter[/name_m]. Also you could use [name_m]Petey[/name_m]. I really like the name [name_m]Peter[/name_m], btw.
[name_m]How[/name_m] about Peep?
There are two Peters in my family. One goes by [name_m]Pete[/name_m] and the other one gets called [name_m]Petey[/name_m] (by his mom affectionately) or [name_f]Petra[/name_f] (by other family members).
Ditto this.
Peep is one of the pet names my brother gets called, although only by family. His friends all call him [name_m]Pete[/name_m].
We used to call him Pika (considered the Hawaiian form) as a pet name too, but he ordered us to stop using that, because of Pokemon. 
I love the nickname [name_m]Pip[/name_m]! Although usually used for the name [name_m]Philip[/name_m], I think it could be cute on a [name_m]Peter[/name_m]. Middle names also play a role in nicknaming. For example: [name_m]Peter[/name_m] [name_m]Oliver[/name_m] nicknamed [name_u]Po[/name_u] or [name_f]Pollie[/name_f].
What about [name_u]Pepper[/name_u]? It has similar sounds to [name_m]Peter[/name_m] and there’s the nursery rhyme “[name_m]Peter[/name_m] [name_u]Piper[/name_u] picked a peck of pickled peppers.” [name_u]Piper[/name_u] could work in a similar way, though it doesn’t sound as “cute” as [name_u]Pepper[/name_u], and is often used as a girls’ name, so maybe not the best idea.
We came super close to naming our last baby [name_m]Peter[/name_m]. We were going to call him Sweet Pea. I even bought receiving blankets with sweet peas on it and my daughter painted a sweet pea wall hanging.
