We took our 5 month DD on a trip to the states over christmas - so -5hr time change as well as a lot of further big trips by car so bedtime routine was all over the place. Usually we put her down to sleep at around 6-7pm, and since 4 months she went from waking every 3 hrs to only around 11pm and 3pm which was great. The night before the flight she slept through 11pm till 6am for the first time!
So now we've been back almost a week, I expected it to take a while before her sleep times adjust but what's bothering me is how unsettled she is now- when I put her down (at a later time as she's still shifted slightly) she's waking up for comfort every half hour till about midnight (previously she'd only wake with hunger), then waking every 2-3hrs for feeds like she was doing a couple of months ago. We're waking her about 1 hour after her old wakeup time to try and get things shifted back to her normal pattern.
I'm not sure whether this is just to do with the time change, or also that she's less settled generally as a result of all the traveling about, or if it's unrelated and she's about to pop a few teeth (though been predicting that one for months).
Anyone else have experiences like this? I feel like we've broken her sleep! Any advice appreciated.
