Hi Kellie...I've had this dilemma in the past too, what time did she last feed? Generally for us, if DD has fed after 5pm then we just leave her to sleep and she generally wakes between 2 and 4am for a feed and then goes back down until the morning. I'm assuming (I know you should never assume) but if she went down at 6 that she had fed not too long before. If her feed was earlier then I would let her wake and then feed her and get her back down. Our DD doesn't sleep so well in the day either but has started having a better nap in the late afternoon - i let her go as I find if we try to keep her up she just gets really tired and grumpy and then doesn't feed well so then wakes earlier through the night because she is hungry. It is so hard i know....they really should come with custom made manuals! Good luck with it all.
