my rule is once you are 2, you are walking lol! I also have a triple stroller but only pull it out if I have 3 little ones. If not out comes the double or single or whatever is needed....He can cry and make a stink the whole way but he will walk...when he gets to the park he misses out on the fun because he wasn't behaving like a big kid...usually only take one instance and they wise up...I have no patience for spoiled and babied kids, at home fine nothing I can do about it, in my home no way lol
