Does anyone have a preschooler who wakes through the night? My son is 4 1/2 and for some reason he wakes up once at least (4 times at most) hes not crying or anything he just opens his door and opens mine (since i heard his door i wake up) i tell him come on time to go back to your bed, so he gets back in bed and falls back asleep. Meanwhile i take 45 minutes or so to fall back asleep and right after im sound asleep he is at my door again... 😩 help! Im so sleepy! 😴
