My usually wakeful 9wk old has slept nearly all day today, only awake for about 6hrs, which has me kinda worried. I've taken her temp which is normal and she doesn't appear unwell, just a little too-relaxed. I guess I'm asking if this is 'normal' - do babies sleep more once they get passed the newborn stage or should I be concerned? Also, should I be trying to wake her up more during the day (she's usually a good night-sleeper and I'm worried I'm going to pay for this tonight!) Thanks!
