I’m an annual pass holder and go to Disneyland all the time! You can take him on almost all the kiddie rides such as Snow White Pinocchio Peter Pan Alice in wonderful and even pirates... I would take extra clothes and blankets because it gets very cold at night time. That’s about it you will have a great time just walking around and seeing all the lights and parades!
You’ll be stopping a lot to nurse and change diapers but since you don’t have older kids it won’t be a big deal to take breaks. You won’t be able to take him on any rides. Are you going with people that have kids going on rides?
Try to take as many breaks as possible
It’s crowded right now
Im there every weekend with my kids
Be patient because lots of people like to push and shove
They act like the rides are going somewhere
But either than that enjoy every second of it
Specially at night your gonna love it
Is there a special reason/occasion that you’re going? I probably wouldn’t given flu season but there are precautions you can take to ensure he doesn’t get sick. Not sure what the flu situation is there, but it is hitting hard here.
