who else's 6 month does not sleep at night!' 😬

My daughter is either up making noises or cry sounds like every 2 hours. Any help with getting her to sleep through the night?? I've tried waking her up early and all! No luck 😩😞 so exhausted!! She only slept like 6-8 hours for like 2 weeks when she was 3 months old and since then no luck!!!
