We have taken our kids at one and they have so much fun. Everything is so new to them. My kids were all fine with the dark rides, but I think they preferred outdoor rides. Mine loved characters at that age as they hadn't developed the stranger danger. My oldest became wary of the princesses aroumd her second birthday and our youngest was past 1.5 when we took her and she is just now warming up to them 9 months later.
Most importantly, take tons of photos and have fun!
YouTube is a big one. Helped with my daughter at that age. Get a cheap umbrella stroller, easy to fold when riding train/monorail. Tie a baloon to the handle so its easy to spot if a CM moves it while you are on a ride. Our first ride with our daughter was the Tiki Room Great ice breaker, lots to look at and loud at the end.
Yes! We always bring a good baby carrier. Lenny lamb, tula, etc.We just took my grandson to Disneyland in January. He was 13 months old. My biggest piece of advice is to roll with it, because you can't predict what they will like/dislike! My GS did not like dark rides (not surprising). He didn't really like rides at all with the exception of Casey Jr. and the Carousel. Unfortunately, many things he might have liked were closed, like the Main St vehicles, Small World, canal boats. He hated riding in the stroller and my dd got very tired carrying him around. He was overwhelmed with the people and noise. The truth is, we decided that in his case he was just too young to really enjoy it, so be prepared to face the prospect that he might not be into the magic quite yet.
You can meet Mickey Mouse with hardly any wait in Toon Town if you are at the gates to Toon Town 5 min before they open. Toon Town opens up an hour after regular park opening.
So if regular park opening is 8 am, then Toon Town opens at 9 am. Toon Town is FULL of fun stuff for little ones to explore.
FYI there is no photographer at that time. Mickey and friends come to the opening of Toontown and walk in with guests to music. Then Mickey and Minnie go to their houses and meet guests outside. He will have a queue and a handler, but they only have the photographer when he's meeting in his movie barn. I didn't get an exact time from the CM on when he meets in the barn but it's at least 20 minutes later and may be an hour even.Great to know Toon Town is an hour later than park opening. Characters are handled somewhat differently in DL than WDW. It looks like there are no FPs in DL to meet them. We will be ready to meet Mickey as soon as he opens the doors!
