The deeper the dollhouse and the fewer windows, the darker the interior. Here are some ideas for lighting up the rooms that your child can do with you.
Purchase strings of LED mini lights. As they become more common, the price is dropping. Tape them to the ceilings.
Only under total adult supervision should flood lights be added. They get really HOT! But, if your child wants to make a video, they’re great. Positioning in front is the best for lighting but too close to the child for safety. I mounted them beside the dollhouse and pointed them through the windows. I blocked the access. The second floor window should be bigger for this.
Another idea is to add battery operated tea lights. They can sit on the furniture.
Little tea light holders are fun and easy to make. Buy craft sticks like this at the dollar store. You also need the little wooden cubes.
Cut the circle away from the handle. Glue the circle in the middle supported by the cube. Have your child paint it gold or white or whatever she chooses.
Tape them to the wall. (Note, tape doesn’t stick well to fabric but works on peel and stick paper.)
Try out other ways of using the tea lights in table lamps, floor lamps, chandeliers. The sky’s the limit.
