he sleeps in a PnP at his sitter's house and today he tried to climb out. if she wasnt there to catch him, he woulda fell right over.

i saw that those tents for the top were on recall for suffocation/strangulation hazards.

any other suggestions on how to keep him in?
my sitter has a 14mo old ds as well so him just sleeping on a mat might be too hard with distractions and what not
