At some stage in a child's life they will go through the "monsters under the bed" phase. If your child does not go through this phase, that's alright as well, it just means their imagination isn't as active or they haven't seen a lot of television.
My cousin was really afraid of monsters. She accidentally saw a scene from a movie when she was at a birthday party for her older cousin and was very frightened. For a whole year my aunty and uncle had to deal with her being scared every night when she went to sleep. She even slept in her parents bed for two weeks straight, and sometimes woke up crying some nights. I'm not saying this will happen if your children see a scary scene in a movie, but it can get quite frustrating as a parent to soothe a child who is constantly worried about monsters.
Strategy one: Get a spray bottle and fill it with water. Rip off the label and make your own call it "Monster spray" or something like that. Keep the spray in the child's bedroom. Before the child goes to sleep, if they seem hesitant or are scared about the monsters, tell them you bought this spray at the shops and its for kids who believe in monsters. Spray under the bed and get the child to as well, spray around the room and let them know that the spray wards off monsters. "I tried this with my 3 year old and it worked after 5 nights. He started to believe it worked and didn't "hear" any more noises like he claimed he did" - Shelby.
Strategy two: Make up a wand or buy one from the shop. Tell your child that you found a spell in a book that gets rid of monsters. Chant the spell together, make up one such as "Monsters under the bed, be gone, be gone!" and wave the wand under the bed. Let the child keep the wand in their bedroom. My 6 year old found a wand at the toy store and was convinced it could get rid of the monsters in his closet. He bought it with his tooth fairy money and used it that night. He managed to soothe himself" - Caroline.
Strategy three: Get a friend to come over and pretend to be "monster patrol". Get the friend to look around the child's room, while the child watches. Get the friend to act as if they're looking for monsters. Get the friend to say something like, "There's no way monsters are in this room. You've got a pink teddy bear and monsters hate pink teddy bears. They wouldn't come in here if you paid them!". If you cant get a friend to do it, do it yourself.
My husband's work friend came over and we got him to have an inspection in our daughter's bedroom. He told her that monsters don't like bedrooms with princess wallpaper on the walls so there's no way they'd stay in her room. She felt more an ease and slept peacefully that night" - Jodie.
Strategy four: Sit down with your child if they start to get upset before bedtime. Remind them there are no such things as monsters, and ask them if they have ever seen a monster in their room Get your child to draw up what they think a monster looks like (in the daytime) and then tell them their monster looks friendly. Get your child to name the monster and write down what it likes to eat and drink. A fun activity like this should put kids mind at ease and make them realise monsters are just made up.
A good idea is to stay away from certain films for children with monsters in them. Sometimes children may watch a movie, even if its G rated and get the wrong idea. Some movies to stay away from (for the time being) are:
Monsters Inc - a funny entertaining kids movie, but the fact that the movie is about monsters who go through children's doors at night to scare them might freak your child out. The start of the movie is quite eerie too even for a child under the age of six.
