we just got back - last monday and dd is 20 months. We took her at 6 months and she was absolutly fine but had a more strict routine at 6 months than she does now so i was a little worried but she was fine. My tips would be on the way out they will be up for 5 more hours than normal if you keep your timings (ie bedtime at home is 7.30 so i wanted roughly the same in disney - so normal time plus 5 hours iykwim lol!) so basically we got her up a little earlier the day we left so she was more tierd so she had a 4 hour nap on the plane (normally has 2) so she had dinner at normal uk time (4.30) and then would normally have bedtime bottle at 7pm uk time so at around this time (was probably a bit later) we gave her a second dinner (so she had brekkie, lunch, dinner 1, dinner 2 and then bedtime bottle) so tricked her into thinking it was earlier than normal and then bedtime bottle at 7pm florida time - my logic was she eats every 4-5 hours and we were gaining an extra 5 hours so just add another meal

. But it worked as she fell straight asleep at 7.30 florida time no probs and didnt wake until 6-6.30am florida time which was perfect for us as we like to be at the parks for rope drop. She was then on florida time no probs!
I think the key to get them onto a different time zone is meals so just make sure you eat at roughly the same times every day. we were a little slacker with her bedtime than we are at home so she was normally going down between 7.30-8.30 and some mornings we did have to wake her as it was getting to 7-7.30am but that was fine as we just made sure she was in bed earlier the next night and hence up at 6.30-7am
Coming home has been slightly different at she has been waking at 10pm thinking she is hungry and wants her dinner

this meant the first 3 nights were quite tough but we never got her out of her cot and just kept reasuring her bedtime, sleepy time etc and then by day 4 she was waking but only for about 30 mins and then last nigth she slept through from 7.30-7am whithout waking so i would say she is back to normal now!!!!



. I think if you stick to a similar routine but just move it 5 hours then you will be fine, if you did some late nights and then some not then i think it would probably just confuse a toddler that is used to a routine so wouldnt advise that - we didnt manage any fireworks as they were all 9-10pm and we thought this would just be too much for dd so we left them til next time when she will be old enough to understand. have fun and try not to worry as i am sure your lo will be fine, i was very worried about how she would be on the plane, in the heat, with the food, with the time difference etc etc but in hindsight i didnt need to as she was fine with them all and had the most amazing time

its amazing to see it through your childs eyes and any teething issues will be so worth it
