Hi
I think firstly it could be her teeth,although luckily she's not waking during the
night,maybe the pain meds are starting to wear off early morning.
Also,both of mine are tummy sleepers ans always have been,so I would
try to lay her on her tummy and see how she goes,maybe try her at the
bottom of the cot as well (we had to do this with Emily)
She could also be having a growth spurt,so check her grobag and just
make sure she can move around comfortably with it getting twisted,this
can also wake them up.
Are you driving or flying?
If you're driving then I would invest in a car dvd player (if you've not already
got on) or borrow one.Excellent for long journeys.I haven't been on a plane
with children yet so I can't offer advise with that.
But I would go with the flow while you're away,try to stick to some routine,
but don't panic if you're out late,you'll only get stressed if you worry that it's her
bedtime and you're out all enjoying yourselves.
4 nights isn't going to hurt her.
When you get home,talk about the trip lots and slowly get back to the routine
will possibly take a few days,but try not to think of that while you're away.
Have fun with hubby
