She may well be having a growth spurt, but the other thing is that perhaps she is really tired because she is changing her sleeping patterns perhaps??

She may be at the age where she starts to alter things a little bit.......just a thought!

How many sleeps a day does she normally have, and how long does she sleep at night (what time does she go to bed?).

Just thinking out loud Deb, tell me to shut my cake-hole if you like! LOL
