My son will be 2 in January and I am due with our second son in February. I am already exhausted from being 32 weeks pregnant and chasing after my son all day (I am a SAHM). For some reason for the last 2-3 weeks, he has gone from sleeping through the night or only waking up once, but going right back to sleep, to waking up 2-3 times a night. He always goes back to sleep almost immediately, but then I have trouble getting back to sleep. I am sleeping in the reclining chair in the living room now because it's too uncomfy to try to sleep in our bed, and he comes in and wakes me up every night. I have tried not letting him have a nap during the day or if he does nap, no longer than an hour. I'm just at my wits end. His bed is also in our bedroom because we live in a 1 bedroom house that we are expanding and remodeling right now. Any advice?
