Hia - I'm fairly new to a pump too and ended up in hospital after the first week with ketones. I'm much better informed now and you seem to be dong the right thing in testing and drinking plenty water. I have a little chart with my ketone meter and it says that 0.0 to 0.06 in the normal range so I'm to not sure if you need to worry about 0.2 as I think this is normal?? My DSN tells me to test for Keynes if I'm feelng unwell (even if BSs are fine). Have you been feeling under the weather at all? I was stressed one afternoon in work and it made me BSs shoot up and I had ketones. Extra bonus with a 5g biscuit, water and taking it easy and it corrected itself within 4 hours.
