Every night for the last 2/3 months, my nearly 4yr old walks into our bedroom during the night and either stands by the door or stands beside me in bed. I always take her straight back to bed without talking expect saying "night night" (previously said at bedtime! She never asks for the loo or a drink. I'm wondering if this is sleepwalking or simply attention seeking/habit. Any ideas?!
I sleepwalked at her age, I used to get into my parents' bed. It passed - I wasn't awake, and presumably your toddler isn't either. Just make sure she is safe and can't fall downstairs. Is anything bothering her?
If you have stairs, put up a gate. My sister did this for years and my mum had to block off the top of the stairs at night in case she fell down them (dunno if you could get stair gates then but my mum used my headboard!). She also got into the habit of thinking she was going to the loo and peeing the end of my bed :(
