I get these sleep sack in several different color b\/c my daughter spit up or have diaper leak so often . as with many if not most other toddler , she kick off she blanket several time every single night . these solve the problem ! depend on how cool it be , I pair they with either short-sleeved or long-sleeved top . they be very roomy in the bottom but now that my daughter 's 18-mo , I leave they half-way zip so that she can move she leg about . -lrb- slightly defeat the purpose but now that it be June , and not to mention , she like it on the cool side , it be okay to have bare leg . I just want at least she torso to be cover -rrb- . she would be complain for the last couple month about not be able to move she leg round . I have also get she a wearable blanket for toddler and get to use it for two night before she diaper leak ... however , that be for another review ! bottom line , I love these sleep sack and highly recommend they .
