I went on a picnic yesterday with my aunt and cousin. I cheekily asked my cousin why she got a special seat while I had to sit on the picnic rug. She offered to swap. My aunt then asked if I would like to sit in it until my cousin wanted it back. Still being cheeky I said yes. She adjusted the harness height and length, I hopped in, she put my arms through the straps and buckled it. I spent the next hour in MY new stroller lol. Some big 13 year old escape artists can't get out either. :)
