JazLyn was born with heart defects. Heart defects cause other issues with the brain. JazLyn knows no boundaries she is functioning at an 18 month level even though she is 23 months old. She is out growing her pack n play and will need to move to the next size bed. JazLyn does not do well going to sleep unless she has boundaries..this bed is for her safety so she don't fall out but also so she can't just get up and roam in the night getting into things that's harmful to her.she has developmental delays and she would benefit from this bed alot.
