In the past month my 6 month old has gone from sleeping through the night or getting up once to waking up 6 or 7 times every night. I am literally getting 2 or 3 hours of sleep a night. I'm not the mother I want to be. I don't even feel safe to drive a car. He's had a consistent bedtime and routine since he was a newborn. I don't know what else to do. I even borrowed a playpen and have tried putting him in there at night, but that just makes it 100x worse. Please help. I wouldn't mind getting up once or twice at night, but I feel like waking up every 45 minutes at 6 months old is excessive. I nurse in bed and am sometimes able to sleep while nursing, but sometimes I just can't get comfy or he's too wiggly.
