The various compartments are ideal for our situation. The urge compartment is used for the emergency pacifier (which here is still plenty of room).
The lower part is for diapers, wipes, cream and "dirty laundry" (if then some games goes wrong) reserved, so the Ersatzanziehsachen, Kuscheltuch, cuddly toy and lunchbox still have enough space in the large area.
The side pockets are large enough for a bottle.
Our little daughter is her backpack with 1 1/2 not yet bear alone, but devices (abdominal belt) are present and for small children well adjusted.
PS: I have also awarded 5 stars for fun and play factor, although this applies only indirectly. The zippers can also be opened from the kids :)
