My 2.5 year old moved into a big bed this summer. She is in a small double with rails to protect her from falling out.
All summer I've not really used a sleeping bag, as it was too hot anyway. I would cover her up with a thin blanket and then periodically check on her and cover her back up. But sometimes I wouldn't and it wouldn't be an issue, as it was hot anyway.
Now it's colder. Her room is around 20-21 degrees at night. She always kicks the covers off and never covers herself back up again. It's stressing me out. I'm up all hours covering her up. I've decided to start using a sleeping bag on her but now I'm stressing that she will hurt herself when she inevitably gets out of her bed in the night or in the morning. She often gets out in the night and looks for me. Now she has the sleeping bag on, she won't be able to get out as easily. Getting out isn't that easy anyway. She can only get out from the foot of her bed, as the rail is lower there.
What did you do at this age ?
