Am getting stressed trying to figure out how to secure the front car seat to the buggy. The head of the car seat is hooked ok over the bar but the foot is just there and can be tipped if you went over a bump. The manual is rubbish and just shows a diagram (and I use the term loosely) of a strap but not where you get the strap from. I HATE INSTRUCTION MANUALS!!!!!! Anyone help as I don't feel that my child would be safe in this seat as it is now.
