My son had always been a good sleeper and has been sleeping 12-14 hours through the night since he was one years old. Now he’s 18 months and for the past week has been waking up once or twice and it’ll take HOURS before he’ll fall back asleep! Last night he was literally up from 1:30am until 6:30am when he finally passed out in my bed. Is this normal? And what the heck am I suppose to do?? I’m also 5 weeks pregnant so it makes it so much harder not getting sleep 😩
