Fussy Fussy

Laila is super fussy today. Normally when she first wakes up in the morning she smiles nonstop for at least an hour. The smiling slowly lessens and about two hours later or so she goes to sleep. Today she smiled a little bit for about an hour and then cried and cried and fell asleep. All day she has been extremely fussy and has been sleeping on and off all day, whenever she wakes she just cries. We took her temp - 99.5 (not considered a fever at this age)... but just because she doesn't have a fever doesn't mean that she isn't sick. She could be sick, or maybe she is going through a growth spurt or something. This is putting the whole trying to get her to sleep in her crib thing on hold. Which actually went pretty well yesterday - she slept in it for half an hour two different times. I don't want to try it while she is so fussy though - I know she would just wake up right away and then scream and cry for a good long while because she would be so upset that I put her down.
