I just wanted to see if a baby bed pal and wedges are safe for a baby to sleep in.

Red Nose does not recommend the use of any sleep positioners, including wedges.
“Do not use any devices designed to keep baby in a particular sleep position. These can be dangerous and they are not recommended.”

Is there a specific reason that you wanted to use this product?
How old is your baby?

Why is baby bed pal not good ?

Red Nose does not have any information about this specific product, however we do recommend you avoid any soft, padded sleep environments.
Red Nose recommends that baby is placed for sleep in their own safe environment, usually a cot or a bassinet, on a firm, well-fitting & flat (not elevated) sleep surface.
Any product that has soft padded sides that are “soft, warm & cosy” does not align with Red Nose recommendations.
