8 months old waking every hour

🎀 • Mum of a wee munchkin 😘
Hello April mommies 
Quick question for you all, my little one is 8 months now and hasn't slept through the night yet, until 6.5 months he was waking every 3-4 hours for feeds but after 6.5 months he started waking every 2 hours and these day he is waking up every hour or so. I'm hardly getting any sleep, we have tried to sleep train him too but nothing seems to be working, does anyone know what could be done to help us both?
Thanks
