Is it safe to use the stroller in full recline position?
Never use the stroller in the full recline position unless the pop-up enclosure is up, because a child may slip into the leg openings and strangle. Additionally, do not use the pop-up enclosure with an older child that can lift up on hands and knees or crawl out. (Page 2)
