If you’re at Disneyland with children too young to go on the rides, take advantage of the “switch pass.” You can wait in line with your whole party and they’ll give you a switch pass which allows half of your party to go on the ride and the other half to go in the fast pass lane when the others get back. That way there’s always someone to stay with the baby and you don’t have to wait in line twice. Switch passes decreased the time spent waiting in lines.
One of the “cast members” at the beginning of the ride line will give you the pass and they have them for all of the big rides, I think.
