Our 6month old son been a fantastic sleeper until last month when he got two teeth through. He now very clinging and won't sleep unless he in my arms or in our bed, which i don't want as my other half a very heavy sleeper. I have tried every night to get up and put him back but its becoming very hard and tiring Anyone got any advice or ways to try and get my son to sleep back in his cot? Been looking at the sleepyheads but not to sure. Thanks
