My DD was wrapped until she was 7 months old. I was worried that she would be the only toddler still being wrapped, than one night out of the blue, she decided she didn't want to be wrapped anymore And that was that. She still loves 'Mr Wrappy" takes him everywhere.
I agreee, trust your instincts, he will let you know when he is ready.
Although hsving said that, I'm trying to ease DS put of his now, but I think he is more ready than she ever was.
Good Luck.
