My son won't sleep longer than 2 hours. And most nights I'm lucky if he sleeps an hour. I'm seriously so fricking tired!It's so frustrating and I'm exhausted beyond exhausted. He's 7 months old he should be sleeping for longer periods of time. I don't get it, no matter what I do..😫😫😫 he has horrible separation anxiety and idk how to break him of it. But before his first sleep regression he would sleep 3-5 hours then after his regression he never really got back on track. But lately it's worse than usual. God give me strength. I feel like there's no light at the end of the tunnel 😔
