Hello Hayley! Oh, my memories are still very clear. The only difference is your 2 year old was my 4 year old. Let me just put this out there.....nap, nap, nap! I wanted to be "Super Mom" and I wanted to be out there keeping up with my 4 year old. After the first day, I realized being "Super Mom" meant heading back to my resort and letting everyone catch a nap in order to tackle the rest of the evening at the parks. Not only was my 4 year old rested and happy, but my ankles and my body were rested as well. I did not know what was more mentally exhausting, putting up with a toddler that had no nap or dealing with my tired body. Really, I saw no difference. A nap was in our schedule from the second day on.
Now while you are enjoying the parks, I would really make an effort to schedule in every parade. This was a great time to just sit and relax and enjoy the Disney magic. Those few minutes really made a difference and gave me the extra energy to continue on. Try to take some time and sit in an area that is not crowded and relax while your little one burns some extra energy by running in circles. Every time my little one fell asleep in his stroller, I used this time to just sit and admire my surroundings. I knew once he woke up, he would have me waiting in lines once again.
Again, I cannot stress enough the importance of taking a nap. I know it is hard to do this because you really want to utilize your time well while at Walt Disney World, but your body will thank you for this.
