California Natives

We’ve booked our “baby moon”/family vacation to San Diego in May. I’ll be 16 weeks pregnant and have a 21-month-old. Any recommendations on what we should do? Debating on the zoo and LEGOLAND maybe Catalina island if its kid friendly but I don’t know. Heeeelp!

Also any tips on flying with a 21-month-old? He’s only flown once before at 6 weeks and that was an absolute breeze but now that he’s older I’m stressing myself out.
