You Won't Like This Present as Much as I Do! — Lauren Child

Lola wants to buy Lotta a special birthday present and thinks up all sorts of imaginative gifts, like a musical jump rope or wings so Lotta can fly. After Charlie reminds Lola that a good present is one Lotta can actually use and that actually exists, Lola settles on buying a doctor's kit. Trouble is, now Lola wants the present for herself!
