any other suggestions? i think we'll probably stick with our Ergo idea. its not the safest but he LOVES sitting in big people chairs right now so its working. but we are thinking if there is something better and easy/light (that would fit in a bag or suitcase and not take a lot of room), we're open to that purchase for a trip we are taking where they don't have highchairs usually, if at all.
I've seen people do the same thing with a mei tai--a mei tai might be a little easier because you can throw it in the wash easier than an Ergo and it's lighter weight for throwing in a purse and traveling.
