hi everyone -- just wondering what age you would feel comfortable having your LO's share a bunk bed/have a LO on the top bunk?

my boys are 16 months apart, and we were considering putting them in a bunk this fall, when LO3 is arriving, but talking to mom friends they've said the boys are too young. i'm still on the fence! I can accept if i'm totally nuts and should wait a few more years :).

LO's will be 3.5 and 2. I'm not that worried about the actual sleeping/rolling off, but more just general safety. Their room is tiny, so it won't be a place with toys etc, although I imagine they would still play in there from time to time.

ETA: I just checked and Health Canada recommends no top bunks for kids until 6 years old.
