I see your point, as traveling alone with a young baby is harder, but I guess I just have a different idea than most and prefer things the old fashion way. I was alone most of my daughters first year and had no problems with out this or other contraptions. Never used a baby bath, crib, pram, stroller, or diaper changer etc, so sure did not need this.

I did use a sling a lot which allows one to have hands free for every need & even allows one to nurse a child while standing in line for groceries at the store with no one the wiser. ( I did that a lot).

Why not just wear a sling with your baby? Keeps hands free everywhere including bathrooms. I used mine constantly when out and about, took up no room, was washable and organic. Baby loved it and I loved it.I never worried about getting dehydrated, nor tried to postpone going to the bathroom.

If one breast feeds and does family bed, that is all one needs IMHO. A sling ( possibly a Bundler too).

The rest is just endless marketing to try to make people think they need "stuff" that they don't. I prefer to think simple like native people and invest my money (saved from buying such things).

I think babies are much more simple than the marketing world makes them out to be. My mom raised 4 in the fifties with none of the crapola we have today. ;)

I want more experiences and less stuff. But, hey, if it works for you or others, that is cool with me too!!
