At three months my ds dropped his night feeds and started sleeping from 11pm - 7am. However, from 4.00am onwards he wakes making very growling/screaching sounds which get louder and louder. Often a dummy will satisfy him but then he spits it out and it starts all over again and this pattern continues for the rest of the night. I've checked all I can think of to make sure he is comfortable - he isn't hungry or too hot or too cold; nothing makes any difference.
Has anyone else had anything similar?
