I need some help making some decisions...

Spring break is coming up...and what better time then stay up all night breaking one of DD's habits.
I just dont know if Im jumping the gun...
DD sleeps in carseat b/c of reflux. I tried to lay her down yesterday and it was NO GOOD. However, Im not sure if its because she dosent like being flat or the reflux. I think Im gonna wait on this one.
Then to the swaddle. DD naps and sleeps in it at night. She cries when she first gets in, but sleeps right after. During naps she struggles to get out if loose, and once the hand pops out shes up. She pulls out the binkey. Now at night she dosent do this. She sleeps through the night (so grateful) and Im not sure if I should mess with it. Being that I have 1.5 weeks off, do you think I should tackle it? Or am I messing with a good thing? DD is 4 months and has to get out eventually, but I was thinking maybe wait until we can CIO?
WWYD?

Re: I need some help making some decisions...

Eva also slept in the carseat b/c of the same thing ( she still does for an hr or so) !The reason we still do it is b/c she falls asleep right after her bottle and we she will spit if we lay her down right away , so we wait an hr or two !!

What we do now is ,when we know she is fully sleeping we then pick her up and put her in the crib ......she woke up the first few times ,but now it doesn't even phase her !
