PSA- it seems a lot of CRes are not up-to-date on current baby safety recommendations.
Nothing- emphasis- nothing- should be put inside a baby’s crib except the baby.
That means- no blankets, no pillows, no stuffed animals, no padded bumpers (this is a new one). The same would apply with draping these items over a crib, since they can easily fall or be pulled inside.
So Tallis is no worse or better than any blanket and it is quite dangerous to drape one over a crib!
To keep a baby warm, use a blanket sleeper or specially designed swaddling blanket that stays wrapped around the baby in place.
Today’s regulation standard cribs have slats that are close enough together so that baby’s head cannot fit thru, so there is no need for a bumper to prevent a baby’s head from getting stuck.
If you think that this advice is extreme, I can tell you about a child who is permanently disabled and institutionalized because someone draped a coat over her carriage and it fell inside and smothered her.
