[LOTR/Hobbit] How long does it take for an elf to mature?

With such long life spans are they children for longer periods of time or another maturation process completely different from ours?

Mentally, elves actually develop more quickly than humans; for example, elves learn to walk and speak before they're a year old. Physically, they age at the same rate as humans until around the age of 3, after which their growth slows greatly. Elves only finish growing between the ages of 50 and 100.
