Is it safe for overnight sleeping in the bassinette?
Hey, Zee,
The newer, very well-ventilated Bugaboo carrycots (e.g. the Fox's) are already suitable for overnight sleeping, but this older version never was tested to that and doesn't have enough airflow to truly be sure it will be safe. So my answer here will be no, don't use this for overnight sleeping of your baby.
Your -very berry- Eli.
