T.,
I'm not sure I have an answer for you (though I do have an idea), but I do know (based on what the child sleep experts say -- see "Healthy Sleep Habits, Happy Child") that you absolutely do not want to put down your baby later in the hopes that she will sleep later. First of all, you want her to sleep about five hours later. Second, waiting to put baby down will cause her adrenaline to kick in to keep her awake when she's really tired enough to sleep. You don't want to create a problem putting her down, too, and that's what supposedly happens. The saying goes, sleep begets sleep. Technically your baby is sleeping through the night (for what that's worth!). What our pediatrician (and the book I referenced) always told me was to keep middle of the night interactions as low-key and perfunctory as possible. Keep the lights off, feed or change diapers as necessary, do not speak, bounce, rock, or otherwise stimulate the baby. She might just be more prone to stimulation than your other kids were or she might think that you and her dad are signalling that it's playtime. Instead of bring your daughter to your bed, which is probably stimulating for her, you might want to try feeding her in her room. If you are breastfeeding, will she take a bottle of expressed breastmilk from dad? I know lots of families, ours included, that did that. It's important not to coo to the baby, etc., as that signals playtime. Perhaps with less stimulation and no cues saying that it might be playtime, your baby will fall back asleep more quickly. Final thought -- is she getting to a developmental milestone or possibly teething? Either can cause disruptions to sleep patterns. I hope you're able to get more sleep soon!
