DD - 6 months old - has always napped well. A couple of times a day for 1 1/2- 2 1/2 hours. All of the sudden she won't sleep any longer than 30 minutes at a time. It's been going on for about three days.
I'd think teething if her night sleeping was being affected. But she's sleeping the same at night as she always has.
It's so sudden, just thought I'd ask if anyone has any idea what might be causing it.
