DS#1 was wrapped for ages, i can't exactly remember till when but somewhere between 8 and 12 months. I just started making it looser so he could still feel it around him for security and after a few weeks got to the point of just laying it over or next to him. Once he was happy with that he used it as a security item so as he got older i chopped up a coloured piece of cotton material (similar fabric to a wrap) into handkerchief sizes for him to take to bed and have as his comfort item, this lasted until he was 3.5yrs, he took it in his pocket to preschool to have at rest time and to settle with at home if upset and at bed time.
