I received this question and I honestly don't know how to answer. The parents want to thru-hike the Pyrenees with their then 3 month old baby, a hike which should take them around 2 months. Even if not following the Pyrenean high level route, the trail will often cross rough terrain and high level passes. I don't think the parents can be persuaded not to do it with such a young shild. They do seem to have enough experience with long distance trails and have reduced their full pack weight to around 8 kg with some food and 2 liters of water. But even before trying, I would first like to hear from others which experience they have with backpacking with such a young child and if they think this is both possible and responsible.
