Ohohohohoh,......no. I say she is definately too young.
The pablum in the bottle to get them to sleep through is a myth if I am not mistaken. At 2 wks old, she is no where near ready for this. Babies at this age need to wake to feed as often as they do.
I also read something about babies being able to sleep through when they get to 10 lbs....well, ds was 10 lbs at a week old and was no where near sleeping through.
The fact is, when she is ready to sleep longer, she'll likely do it!
