my wife and I love put we toddler in the Halo SleepSacks . between the flannel one for winter-time and the mesh one for summer , there be sack for every season . when he be younger , we really appreciate know that he be comfortable while sleep but will not have " safety " related issue that be introduce with blanket . as a older child , we like that the leg be " penguined " in a way that prevent he from throw one of he foot up and over he crib rail -lrb- probably not what be intend by HALO , but we 'll take it -rrb- . I simply wish there be a adult version that do not look like a snuggie .
