just looking for some advice as I am quickly heading towards exhaustion! my 17 week old DS was a really good sleeper going down at 7pm at 6 weeks and sleeping through at 11 weeks without any prompting from us. however over the past few weeks he has stopped going down at 7 and most nights will not settle in his cot. occasionally he will sleep for a couple of hours in it and then wake up crying. he then ends up in bed with us. recently he has also been crying when I try to put him down on his back and will only sleep on me or in his bouncy chair. has anyone had any experience of this? will it pass? I am going back to work in January and I really hope it all settles down again by then. thanks for reading.
