I had my interview today. our lawyer was also with us. It was good and took about 30min. first took oath and then asked almost all the Questions from I 485. checked our marriage certificate, I 20, passports, DL, baby's birth certificate, and tax returns, medical insurance only. finally she said all good and she has to show it to the supervisor and will approve it today itself if a visa number is available. she hasn't checked the bulletin. So I hope everything is fine and I will get the approval. waiting for the update.
