My baby is 6 months old. He has always been a great sleeper and has been sleeping through the night for a few months now but for the past two weeks his sleep has been getting worse and is now waking up every single hour of the night, sometimes more often. I am getting next to no sleep at all and am getting really worried as it is so unlike him. He is teething at the minute, could this be the reason why he is sleeping so bad? And does this stage pass on its own and return back to normal sleep pattern or is there anything I should be doing to help?
