Hi, We're just looking at purchasing a child bike trailer for our two daughters (currently 2.5years and 6 months). I looked at the Croozer Plus Kid 2 this morning and the Burley D'lite and Encore this afternoon. I loved the look of the Burley but it doesn't have the option of a baby sling. Has anyone tried putting a different brand sling into a burley trailer? Chariot, Croozer and some others all market them.
