After reading this, I think it might be what is happening with my 13 month old daughter. She slept easily til she was 5 months (laid her down still awake and left the room) and she learned to roll over and sit up. Since then it has been a pu/pd (and now just pd, but no crying) battle. The last few nights though, she has been screaming her little heart out at bedtime, and she only settles when she is in my arms (I always check her bum first, and give her Tempra if she seems in pain - she's getting her molars) but as soon as I put her down she cries. Last night she went down hard at 9:10 (usually she is in bed at 8, and we started the process on time...over an hour of screaming and she fell asleep finally and instantly in my arms when I picked her up to check her diaper again). Then she was up again at 12:20 and would NOT let DH leave the room or put her down. She would just sit and scream. She did this til 4 am, and then got up as usual at 6 am. The thing is, DH just returned from an 11 day trip to Kong Kong, and he has never left her before. She was fine when he was gone, but now seems to want to never let either of us out of her sight again! Any advice? We want to have another child soon, but we need to get her back to just laying down and going to sleep on her own first!
