We had an Amby hammock and I loved it sooooo much! Oskar slept through the night really well in it, it looks quite comfy lol. He was in it until around 6 months and that was only because he started to roll around too much in his sleep. Had no probs transitioning him to the cot cos he used to sleep on our bed or cot a lot during the day as he just never liked the hammock in the day, only at night. He was ready to have more room to move around I think.
