DS (13 Mths) used to sleep really well and go to sleep on his own and self settle when he woke in the night. For the last three weeks it has been going so badly wrong. He is teething and getting four molars at the same time so we have just put it down to this and keep thinking once they are through all will be ok again. They are pretty much through though and things are getting worse not better. at bedtime now he is fine and happy, we put him in his cot and then leave and he instantly starts screaming and getting REALLY upset, he will only settle again if one of us stands in his room next to his cot or pats his back, this will go on for up to a couple of hours, then when he wakes in the night it starts all over again - he's waking about 2-3 times a night. We are so tired and just don't know what to do anymore. Do think this sounds like separation anxiety at night or has he just got into a bad habit from all the teeething trouble. How can we sort this out as we are just shattered now!
