No, only my wife was allowed in

Philippines. 
 
More than likely need to officially change the name through the courts there or here.

*** Moved from Bringing Family of USC forum to the Philippines regional forum, for country-specific input ***
 
 
Easiest to change the child's name after US immigration.  Your spouse is planning to adopt your child anyway, right?  You can do a name change for the child as part of the stepparent adoption process.  Minor child name change petition (without adoption) through state court is also an option.  Either option is a much more straightforward process in the US than in the Philippines.
 
To change the child's surname in the Philippines would require a PSA birth certificate correction or a name change through the court system.  PSA BC correction would not be an option for changing to your spouse's surname as your spouse is not the biological parent.  Surname change through PH court order would only be an option after the child turns 18 years old.
 
 

Your plan to reschedule your oath ceremony after you return to the US from your trip is good 👍  Are you a Philippine citizen?  If so, remember that legally, your PH passport is voided the moment you take your US oath.
 

My recollection was a couple weeks the letter came in and it was about two weeks later she took the oath.  Interview 11/17, oath 12/17.  I sort of flagged your trip for comment because the whole puppet show might be missed.
This was Houston, all the offices are different. 

FYI our oath ceremony last year was about a month after the interview.  Based on what you’re saying it would have fallen in the middle of your planned trip.

At the interview it would be good to carefully explain your situation and ask for your ceremony appointment to be scheduled a few weeks out.  

Traveling between interview and oath wobble a problem unless you violate physical presence requirements.  

Attend the appointment. Decline same day oath.  Inform ISO of your travel plans. Don’t miss the second oath appointment. You only get two chances. 

If you are offered a same day oath ceremony you can get your passport in time if you can work the logistics

you can get a passport for emergency travel. It requires an in person visit to a passport office .. my closest one was 5 hrs drive each way.. and some careful timing in booking an appt .. appt xan only be made via phone no more than 10 business days prior to the travel date 
 
10 business days before your travel, call the number on the link above and get an appt at the passport office. Have your booking details in hand as you will be asked for the record locator 
 
Attend the oath ceremony and receive your certificate. 
 
Fill out and print the passport application. Consider applying for a passport card also. Get your photos printed. Gather any other documents required .. birth certificate, marriage certificate etc  .. and photocopy your naturalization certificate.  ( several good quality copies)!
 
Attend the passport office appt.. hang around for 2-5 hrs .. return to the office and pick up your passport and naturalization  certificate 
 
return home
 
breathe 
 
pack 
 
enjoy !!! 

I don’t know for sure what your FO is since your timeline is out of date. If Chicago, https://www.visajourney.com/timeline/citlist.php?op6=All&op7=Chicago+IL&op1=8&op2=&op4=1&op5=5%2C10%2C11&cfl= same day oath doesn’t seem to be a thing. 

Get the passport office appt then if you dont get offered same day oath just cancel the appt and travel on home country passport and GC 

Not Pennsylvania, but to give you an idea of costs, I hired an attorney in Kentucky and start to finish was $1000 and 7 months. Most of the waiting was background checks on me as they missed that I lived in three states in the past 10 years. 
 
My employer has a benefit that covers adoption fees up to $5000 so it was an easy choice to go the lawyer route. New birth certificate issued about 6 weeks after the final hearing. 

Your own Family Law Courts have a Legal Aide clinic and will also be able to refer you to any non profits or Family Attorneys that offer pro bono ( free) limited scope help. 
So I recommend, you start by making some calls and even take a trip there to get local referrals. As you said, it is a legal process through the Courts that you are trying to DIY . Challenging but possible and I am sure many will help you. 
Good Luck 

Here you go , a complete guide. Read it slowly and see adopting a foreign born child . Good luck

Thanks that's about the only good resource I could find so far.

Oh yeah that part is already determined. We're just trying to do all the legal stuff too.

Got it, thanks. Another NYC trip it is.

They would only tell you to go to the consulate that handles your jurisdiction.

Based on your other thread, you're referring to your stepchild, not your biological child, right?  If so, the I-130 requirement you quoted above is not the one that applies to you.  For a USC parent petitioning a stepchild, the family relationship evidence you must submit are: your marriage certificate with your wife (the child's biological mom), the child's birth certificate, and marriage termination documents of your prior marriages (if any).  That's all.  Refer to item H on page 8 of the I-130 instructions -- https://www.uscis.gov/sites/default/files/document/forms/i-130instr.pdf
 

You can petition her and say 18 months or so.
 
Adoption well a State issue and i have no idea.

You as the USC stepparent should file an I-130 for your stepchild.  The immigration process will take 1-2 years.
 
Do the adoption AFTER the child immigrates to the US.  Stepparent adopting a spouse's child is fairly easy to do in state court in the US.
