Hi I purchased a quinny zapp today. While I was in shop I tried to fit the footmuff to see how it looked. mmmm... I may be being really stupid but when the strap for between the legs is inserted through the slot in the footmuff, it doesn't seem to leave any room for dd legs. Kind of difficult to explain.The hole for the strap is quite low down so the depth from that to bottom where it zips round is shorter than what her legs are!!!!! Can anyone help
