Adjustment of Status - I-485

Hello everyone,
I had my interview yesterday in Santa Ana, Ca.
Everything went well. I’ve been married to my husband for more than 4 years now and we have a child together.
I got to the building 15 minutes prior to my interview, by the time we were done with checking in, it was about my interview time, then we went to a waiting area and I didn’t really stay there for a long time (5-7 minutes of wait in the waiting room). I went to my interview with my husband, our child and our lawyer. The IO came out and invited myself and our lawyer back in his office, my husband and kid stayed in the waiting area. The interview itself was very short and easy. I was only asked questions about myself, name, DOB, address, if I am adjusting based on marriage, name of my kid and date of my wedding. Then the IO asked me yes/no questions, but he was going very fast through them and grouping them together, so it wasn’t intimidating at all. The IO was like a friendly doctor, he was asking questions, taking some notes, keeping social conversation and making jokes. I didn’t feel that he wanted me to fail. My interview was very short, 30 minutes max. The IO didn’t look at any of the supporting documents, he didn’t ask me the name of my husband or anything about our wedding day and/or married life. I asked him if he needs to look at my pictures, he said ok. Looked quickly thorough them. Then he told me that I will receive my green card in 30 days and printed me white paper. By the time I was out of parking garage, my online status changed to “new card is being produced”.
My pd is July 2019, original interview was supposed to be in March 2020, then on August 4 I got a phone call saying that they scheduled my interview for August 11.
