Read charts...circular needles

this may sound crazy but i am trying to read this chart and my question is …am I suppose to knit each row twice before moving on to the next row or just once? I am trying to make this cute baby hat for a family member who is expecting a baby next month.
thanks for any and all help.

Each row is only knitted once. Of course because the heart motif goes all the way around the hat, the rows will be repeated around but after one full round of knitting you will move onto row 2 of the chart.

Oh, and because you are knitting in the round, every row will be read from right to left.

ok thanks, so I was doing it right.
