Since 2 weeks ago, he no longer goes to bed on his own but he wants mummy and daddy in the room with him. When he wakes up in the middle of the night, he will scream and cry for us too. A week ago, he climbed out of his cot to look for us in the middle of the night. Since then, he has been sleeping on a mattress on the floor as I do not want any mishaps to happen.
We are really puzzled with his sudden change in behaviour. This happened after he was down with fever. However, from past experiences when he was sick, he'd go back to his usual, independent self after he gets well. But not this time! He was sleep trained at 7 months plus and since then has been happily sleeping in his own room. We just need to put him in his cot during nap and bedtime, sing him a song and leave the room. He'd then talk/sing to himself and slowly self-soothe to sleep. So what's wrong ar? Separation anxiety starting to peak?
