Suddenly shorter naps

[vlooby]

The last week or so my 8 month old has gone from having a 2hr nap and an hour later on, to one hour in the morning and 40mins in the afternoon. Doesn't seem to be teething and night time sleep isn't affected. Problem is she seems over tired during the day. Any ideas?

If it's a sudden change, I'd suggest illness. Cold, sore throat, ear ache, etc.

Funnily enough she's woken up this morning sounding all snotty. Thanks @FATEdestiny
