After dinner naps

[billy]

Hey billy,
This is a nice piece because it could have easily fell into sentimentality given the subject, but it doesn't. I do have some thoughts:

After Dinner Naps -I feel like any parent will appreciate the pluralization of "Naps" here.

I could smell cabbage on her breath.-A gross opening, but it does a good job of catching the reader's attention.
A few large particles of it were glued on her pristine white peggies;
three of them like miniature marble tombstones spattered
with lichen, moss and slime.

A hefty burp exploded, -I feel like "exploded" isn't needed here as it seems to be a bit redundant to me.  You could say something like "A heft burp reinforced the image of..."
reinforcing the image of a small Shrek at a dinner table. -I'm torn on the Shrek image. On the one way hand I think it's appropriate, but then it is a bit dated. However, being a dated reference reinforces the speaker as a parent because we make dated references all the time. 
Neon green sticky vomit projectiled over a toothy grin,
a satisfied toothy grin.
she/it put chubby inflated fingers to her mouth then played
patticake on my face. -I wonder if you would consider turning "patticake" into a verb here and say something like, "then patticaked my face"? Just a thought.

My shirt cried a little as my bellybutton inhaled the moisture. -I found the imagery in this line incredibly odd, but that's a good thing because it made me reread and enjoy this line numerous times.  
I wretched a little as the bubble blowing  face
flopped onto my mouth
like  she were trying to resuscitate me
with the gurgle of a slit throat. -Personally, I found this image a bit inconsistent with the rest of the poem up to this point. A "slit throat" seems out of place to me in the context of the rest of the poem.
Gooey fists slapped my ears,
wiped themselves in my well groomed hair.

After a few splutters she rested,
her head lifeless on my shoulder,
seemingly devoid of neck bones or cartilage. -This is a nice image because it reinforces the idea of the child as some sort of monster.
A wisp of breath brushed my ear
as a silent trump rustled her diaper. -I like this reference to poop. Any parent can sympathize with it.
I joined her soft snoozes with my own;
two happy dozing monsters. -I quite like the last two lines. I wonder if the speaker considers himself a monster because of thinking about the "gurgle of a slit throat" and "her head lifeless"? Or is the monster reference just reinforcing the sense of togetherness between a parent and their child? If your attention is the first interpretation, then the "slit throat" image should probably be kept.

I hope some of what I said is helpful, and I look forward to seeing where you take this piece from here.

Thanks for the read,
Richard

thanks for the feedback richard; will think about patticakes and will think about the slit throat image.
