Almost three year old DS's sleep seems to have massively regressed for no obvious reason. He used to be really happy about going to sleep. Now he has epic meltdowns the minute the light goes off, refuses to sleep, screams and screams and won't let DH or I leave the room. Its horrible. With naps we let it go and just get him up again, as we figure he's due to drop them anyway. But at bedtime its hideous. He's also taken to waking in the night. I'm having a horrible pregnancy and DH is at full stretch juggling work and taking DS off my hands as much as possible, so we really can't take this right now.
