My DDs have stayed in all sizes for ages - they're tiny.

The only thing they grew out of quickly was 0000s that had feet - they were just too short. They stayed in 0000s in bodysuits, legs, and onesies without feet for a good few months though. Nothing to say that this little girl will be like her big sisters, but I've learned my lesson and the few things I have bought new in 0000 are all without feet.

I agree the Bonds sizes are tiny, followed next by Target.
