I love use Halo sleepsack for my son . however , as he be walk , I think we would move up to the leg version . I read review note it run large but ignore the advice . do not . this product do run large ! my son be 14 month and on the smaller\/shorter side and the sack dwarf he . somehow he manage to walk in it though we have to help by pull he foot back through the leg hole . other than that , I love this product . very soft and warm . with a pajama top underneath , I do not worry if he be warm enough at night . to keep he foot warm , we just pull they up into the sleepsack . I recommend this product but wait to use until you child be older -lrb- at least 15 month -rrb- .
