I'm planning to travel (sometimes) alone with my baby-to-be. I will probably starting around 9-12 months.
I will have the ergo and am interested in whether anyone's carried a backpack over an ergo (or similar) also on the back? I tried it with a baby I nanny for, and I think with a few minor adjustments to the backpack I had, I could do it for day packs.
I've also tried the ergo backpack (the one made by ergo to strap onto their carriers), and I didn't like it. I felt that it was poorly designed and would rather alter a smaller camelbak with a build-in water feed (so convenient for all-day hikes) to work.
I guess my concerns would be whether the load in the backpack was uncomfortable on baby's back, and keeping the load at a good height, below baby's head, by adjusting the straps.
Just interested to see if anybody's managed to carry a backpack over an ergo or beco (also on the back) and has experience to share.
