Yes, you are doing the right thing...absolutely won't hurt nothing, they can figure out the rest with the case escalation. Y'all be safe out there! 

CR1 is what you have... if you filed after 2 years of marriage before your i-130 got approved then you get IR1 for 10 years green card. 

I can tell you it was an oversight they don't have his biometric captured as a new citizen. You need to let them know, there must be a mixed up somewhere, this is a country where they dig things when they are ready.... let them know so your son can be properly document, don't let them ask you or anyone close to you later how it happened and never let them know.

You got CR1 because you filled few months after your marriage not the day you got admitted into the US. What status do you have on your visa before you left your country? IR1 or CR1
