Yes, read through the baptismal service. Very moving. Don't get too caught up in the rubrics of it. Even if you were to try to memorize it it would likely escape you in the moment. I was baptized last September so I am coming up on a year. I was nervous going into it because I didn't know what to do and when to do it, but the priest or my Godparents would just take me by the hand and lead me through it. That in itself was an amazing lesson. Congrats.
