My soon to be 3 year old has generally for the last year been very good at night. The last three nights she has been asking us to leave her door open which was previously always closed, and is saying it’s too dark. I just wondered if this is a normal phase and something a night light may help with? She has been coming in with us as she has been so upset and I have been unable to settle her. We have never done this and we have always settled her in her bed but she is older now and I’m not sure how to handle it. I don’t mind if we aren’t setting up the proverbial rod... . What do people think I should do please? Thank you.
