up every 2 hours😭

My son is nearly 8 months old, and yesterday he had a slight temp, very whingy, no energy and sleeping a lot more than usual, I put him down to bed as usual, and he woke every 2 hours and didn't want to go back to sleep. We assume he's cutting his first tooth, I've gave him teething powder, calpol and kept him hydrated. But I'm absolutely exhausted, any tips on how to get a teething baby to sleep at night?
