My son is now 10 months old and has his 2nd week of life up to now (he is about 75cm tall) can take a dip in the tub until it was too small. The sun function enables relaxed bathing for parents and baby, as you sometimes have one hand free. My son enjoys it downright sometimes to sit alone in the tub. The tub is also very light and fits on smaller shelves and in the bathtub. A great tub, which I can only recommend to all parents.
