Oh darl, you are SO not a bad mum for that! The things they do sometimes, you just don't know they're going to do it. We never did up the straps if we were stationary / visiting either

OUCH Stevie, I've done that too I felt like the worst mum in the world, but quick cuddles and kisses, and all was forgotten (on Jazzy's end at least ). We're not the first and won't be the last to do it.
