gosh, Jake is still in 0000 jump suits and won't grow out of them for a while!!!
That's fine, as far as length goes Jazz should be in 000 but as far as weight goes she should be in 00000.

0000 is too small sometimes but too big most of the time. We got her a cute outfit with trackies and a zip up jacket in 0000. The jacket goes down to her ankles and will probably fit her for several months.
