normal, takes time fo her to adjust to your pattern as well.
or you can be like me, adjust to hers, sleeping @ 7-9pm and waking at 3am and accompany her until morning around 5-6am then sleep back

Peachu is starting to cling to me already, she just stays on my shoulders when I wake around 3am and take her out wubbzzz totally cute xD
Now I just let my glider sleep outside her cage ; she has slept in my artcard rolls, canvas, and now my jacket LOL
btw, mine is like yours ; barked three times so far in total, only when I sleep late and wake @ 5am or so, then she will feel longly and bark for attention.
