My 15-week-old daughter used to sleep through most of the night but lately has started to wake up every two hours or so. She will root around, toss and turn until I feed her, and then, while she nurses, she will go back to sleep, often within a minute or so. She won't go to sleep any other way - pacifier, rocking by dad and all the other tricks that used to work don't help anymore. It seems to me she's not really hungry, just thirsty, so I was wondering if it would be ok at this point to give her some water or tea at night. I am concerned that she may get too chubby if I continue to feed her so much at night when she's not really hungry (besides worrying that she may get used to the frequent night-snacks and then want them all the time!). She's always been a big baby (in the 90th percentile for weight and length), but since she's started this habit a couple of weeks ago, she's gained more weight then length and is now in the 95th percentile for weight and 75th percentile for length. I'd like to hear your experiences. Thanks!
