Hi All,
I brought a new wigglebums pocket nap when they were having their sale a month ago... but find I can't get it to fit snugly on my dd.  She's nearly 4 months old, 6.5kgs at last weigh in two weeks ago, so not  a chicken legged bub.  I got the medium as its supposed to fit from 5.5kgs, but I'm finding it gapes badly around the thighs.  I so LOVE the print, but its unuseable 
 
 
Does anyone else having one, and how do you find the sizing??
Thanks
