Hey twinmom, no advice on the potty training, my two have been on and off since the start of the year, the younger of the twins (3 minutes! !) seem to be keen to try most days but has a llot of accidents, at daycare they do ok with it, but the girls that work there have also said that with everything that's going on in their lives at the moment, don't stress too much about it, our s7 was 3 and a half when he toilet trained but also did it in a week, because he was ready.
just my two cents....
