Yes... there is a definitive sweet spot to get the carrier to latch into the stroller. For starters you should make sure that the hooks that the stroller latches onto are actually flipped up. They flip up and down so that way they don't poke the little one in the butt when they're no longer in the carrier. And just for completeness sake the carrier goes in with the baby facing the person pushing the stroller. Won't work the other way. Not that I didn't try the first few times. :)
