DD turned 2 last week & she has slept through the night less than a dozen times. I go to bed when she does most nights (around 830pm), we co-sleep, it's not very often I can sleep during the day but we have quiet time for an hour or so watching a movie & I'll lay on the couch.
Im still not used to it & get teary at least once a fortnight & just keep telling myself she'll grow out of it eventually.
