My little boy is 8 months old and has never been a good sleeper. He started sleeping a lot better at around 7 months but since teething ramped up he will not be put down to sleep unless in the pram. An attempt at controlled crying did not work at all and seemed quite mean. We have resorted to co sleeping, but I'm not sure if it's ideal as I'm worried it could be unsafe and that he will get too used to it...is this just part of the sleep regression at this stage and will he grow out of it?!
