My DD is 3 now, she has autism and has recently been waking during the night screaming/crying. This would happen at around 3:30am, I would go and comfort her and she'd sleep until 4:30am where the cycle would begin again. I've gotten so desperate that I've started taking her into my bed but this causes little sleep for the both of us as she then wants to play or won't settle until an hour or so later. She sticks to her usual routine, usually getting up at 10:00 or 9:00 and not making up the lost sleep.
Neighbour has complained and asked me why I'm leaving my child to cry and how could I be so cruel etc I've explained myself and DD but she doesn't want to listen. She thinks I'm leaving DD in a room to cry on her own and wants to report me. 
This is the last thing I need as I really don't know what could be wrong with my DD. I don't think it's teething as I've given her medicine and she automatically stops crying/doesn't wake when she's in my bed. I'm not sure about night terrors as she is awake. She doesn't just seem awake. She's aware but when I go in she's sitting in her crib crying. It's a high pitched cry and not just a whine but I don't know what this is or what to do. I'm exhausted and at my wits end. Please. Can someone help?
