I'd say no!!
My DD is just two (yesterday!), and we went through the exact same phase about 4 months ago funnily enough!
Every morning she was stripped naked, nappy the lot. Sometimes she'd weed in the cot as a result, other times she did it at night before going to bed.
We did try potty training as thought this was a sign, however she wasn't the slightest bit interested and I don't think the two were at all linked.
We didn't want to push the potty training as didn't want to send her in the opposite direction screaming, and the stripping phase lasted only a few weeks longer.
We now don't get it any more - she also isn't potty trained either, but she'll do it in her own time and won't be going to uni in nappies
