I buy this blanket for we fussy 7 week old daughter and could not believe it - it make swaddle a snap !!! my daughter be a absolute houdinus and could get out of every swaddle blanket we try -lrb- and we be swaddle use Harvey Karp 's method -rrb- - but we try this one and it be the first she could not get out of - so from then on , it be the only swaddle blanket we ever use ! the thing that be so great about it be that not only do it make swaddle a snap but baby can not get out -lrb- or pull fabric up over they face -rrb- . I have buy one for every other friend expect and have always hear great success story ! Worth every penny !
