We are due with #2 on Friday. We bought the Graco Day2Dream bassinet play yard instead of a regular bassinet as we figured it would be more worthwhile in the long-term. We put it together and I'm wondering if the portal bassinet is safe for sleep. The mattress feels kind of like memory foam. It's soft but not too soft. I'm sure it would be fine for supervised day sleep but I'm not sure if this is safe for overnight sleep. Excuse my daughter's toys. She put them there for so brother has something to snuggle with lol
