My 9 week old was sleeping thru the night from 9-5. For the last few nights she wakes up around 1:30-2 am and is sort of crying/restless/kicking but never really wakes up. I give it awhile going she falls back asleep but end up un-swaddling her and going to the couch just so my husband can at least sleep.  I'm not sure what's up with this but miss my sleep already. She's swaddled so maybe I need to stop swaddling her? I haven't been changing her diaper bc I don't want to wake her up but maybe I need to try that? Gas maybe? Any suggestions? Doesn't seem hungry and she will take a pacifier but usually doesn't care too much about it once she drifts off and it usually falls out. I'm desperate for my good sleep as a working mom.
