I am having no luck finding large (size 5 or larger) ONESIES. Isabel's newest trick is pulling her pants and diapers down which is definately not a good thing. I have seen special needs kids older and bigger than her wearing Onesies (snap between the legs and make access to the diaper more difficult) but I can't find them any where. I have looked on the web but am having no luck. I know I could sew some snaps onto a long tee shirt or something but am not very handy with a needle and thread and dont usually have free time for such projects. Does anyone know where I could find any onesies for big kids???
