Swing to crib transition question.

Lyndsey
My son has had reflux, so he's been sleeping in a cradle swing since he was 7 weeks old. I am worried about his safety and need to transition him from the swing to the crib since he's over 14lbs now and 3 months old =/ Do any mom's have tips? What helped! We put him in his crib last night but he had a restless sleep....
