The nap-ban is probably a developmental stage and I daresay she'll be back to having at least one soon. I found I had to be really disciplined, and as soon as my DD would go down for a sleep, whether it be one hour once a day or two hours twice a day, I had to get straight onto my work, no stuffing around. I took the phone off the hook and just worked as hard as I could while she slept. I also scheduled the first couple of hours after bedtime (for her 7pm) as work time. I did this six days a week some weeks. I was only employed to work 2.5days, but had the liberty to spread this out as much as I needed to across the week.

I don't know if that helps at all...
