Around 2 months ago my partner, son and I have moved house, my 19 month old has officially moved in his own room. For the first few weeks he slept very well in his new room. After this he is suddenly now waking up in the middle of the night crying and running to his bedroom door, and won't go back to sleep until either myself or my partner puts him back to bed. I have tried everything to help him but my son is still waking up in the middle of the night and I do not understand why.... I am thinking to speak to a sleep therapist?? Does anyone have any suggestions??
