I had made careful plans to take my 4 yr. old son on Barnstormer first, planning to follow that with BTMRR then Splash, then Space Mountain if things went well. Well, he took one look at the Space Mountain building and said "Cool! I want to do that first"...
While I was very hesitant about it (his sister wasn't nearly as thrilled with this when she was 6) my husband said "Let him do it". I explained that he would be seated in front of me. It is still possible to reach around the seat and touch the person in front of you so I told him I would be holding his shoulders at all times so he'd know I was there. Well, as soon as the ride was over, he looked at me with this HUGE smile on his face and said "Mom, can we do that again? Only this time, would you please not hold onto me!" Figures!
Splash also got the "Cool! Let's do that now!" and he would have done it over and over again if we could've (4 times in a row was my limit)... Ditto for BTMRR... we never did make it to Barnstormer...
