I am probably tempting the fickle gods of sleep by saying this, but C has taken unusually long naps the last two days. She typically takes two 30-45 minute naps at the sitter's. The past two days she has taken two 90-120 minute naps each day. Her night sleep is still good, although she's actually gone to bed earlier than normal the last two nights. What gives??

She's super close to crawling, cruising and pulling to stand, all at the same time and I think she is perpetually teething. Could that be what's going on?
