We tried sweet potato chips for tea yesterday and wow, not one bit of mess. She ate every single one of them really quickly so I can chalk them up as another hit. I'll do her some more for lunch today as they were so quick to do, I just par boiled them for 5 minutes then shoved them in the roasting tray with a small amount of oil. I sneaked a couple in Jack's normal chips too and he ate them without noticing . I'll put some piccies of her with her lunch later.
