I don't do EC w my 8 mo old - well I do put dd on the potty when she poos tho - but that's it. but i think baby potties are completely useless. Just hold them over a real potty. At 8 months dd sits nicely on it with me supporting her so she doesn't fall in. My mom never used potties for us for the most part - tho we didn't use the toilet til toddler age. I had DD on the potty at 3 mo one time for a poo tho too so I think it works.
