Addendum 18:05:14: to wash after a call to Amazon and do the pillow again 2x and dry in the fresh air, we tried it. So wash and left the pillow outside on the balcony. Thus, the pillow stinks no longer so great. Unfortunately but still smells a bit uncomfortable. Head reference plan and the daughter was asleep again today very happy and laid on her pillow. We tried 2 other pillows now. 1. Träumeland cushion moss: is much too shallow, super more suitable for baby under 1 year. Not for our daughter.
2. Salosan Orthopedic Kinderkissen Prima Bambini: is much too high. For children over 3 may very beautiful and super useful!
So ARO Artländer is really almost the only pillow that is very well suited for children aged 1-3, neither flat nor too high. Precisely! Prior Träumeland would be great and then Salosan. We just hope that the unpleasant smell disappears. Therefore, we give the pillows instead of the 1 * * as it is perfect for 4 children from 1-3 and less smelly than the beginning. We would give it the full 5 * if it smells better
