Hello, I also did AOS from TN. The process was straightforward and took 6 months for me. I was able to work the whole time, TN is valid until you receive your EAD/AP card.

Coming back here to update the situation for anyone who needs it. I used the TN visa route and I was granted entry into the US. Note that I have an unapproved I-130 which the border officials saw on uscis’s website at the port of entry. 
If for anything, it’s worth a trial. The worst you’ll get is a rejection. 

~~Moved to Work Visas, from the Canada forum - as a more appropriate forum~~

You should "report" your post and request they re-write the title. 
I'm not sure how many years your partner has before they can apply for US citizenship but you might want to consider filing an I-130 petition for your new born. 
Currently, on the visa bulletin  they are interviewing F2As with a September 2020 PD. So, you will probably wait another year before the petition is approved and then you will need to wait for DQ and being called for interview. 

Hello house. My spouse submitted an application in December 2022 to file for me and we had our baby in 2023. We mentioned in the application that we we’re expecting a baby and attached scans as proof. Our baby does not require a visa to visit the US. 
What do you advise? Should we
1. Send an additional documentation to add our baby to the application?( I’m not sure how this is done. If yes, how do we go about this?)
2. Should we wait till my application is all complete so we can do an adjustment of status for the baby when we relocate to the US since he can enter the US with his passport as a visitor without requiring a visa?
 
 Thanks 

As a GC holder, your husband has an upper hand in that you can include the child in your application. My advice is for him to not apply for naturalization yet as then derivatives are not allowed for CR1/IR1 cases and he’ll have to file a separate I-130 for your baby which will delay everything significantly
