Backstory: LO is 6 1/2 months old and we mostly nurse to sleep at bedtime and she is sometimes rocked to sleep for naps and sometimes put down awake and falls asleep herself (though she does this for her daycare nanny far better than for us). Most nights she wakes 2x and I nurse her and put back in the crib - total awake time of about 15 minutes each. She has gone longer stretches recently, 7h45m and then 9h30m (!!) just last week.

Last night girlfriend had a hard time getting to sleep, was up 4x and then awake for the day at 5:20.

We have been considering a more formal approach to sleep training but I am not sure if this is the right time. We are about to move into a new house and I have read that things like this can cause disruptions to sleep, even after having sleep trained. It felt like we were slowly moving in the right direction but last night was really rough. She has a lot going on right now (new teeth, starting to crawl) so that, plus a move, plus sleep training kind of seems like too much all at once. But when is there ever a time where there's nothing changing?

What would you do? Sleep train now and then help her get back on track after potential setbacks after moving OR wait until after the move and sleep train in the new space (she will be about 71/2 - 8 months old then).
