My ds is 5 months old and has always slept well enough. He moved into his own room two weeks ago and took to it well and even did a couple of 7-7 shifts - great! Cut to this week tho and it's all change. He is waking up after three hours or so and whining for about two hours before going back off; I don't know if there's something wrong or not, he is fine when you pick him up but cries when put back down again. He will sleep fine if I bring him in to sleep on me but I can't do that all the time: have tried bonjella and calpol but they don't help so not sure its his teeth. Does he just want cuddles?! I don't know what to do and am worried about starting bad habits which cant be got out of. Sorry for long post, thanks for reading
