Advice required!! Odd 4yr DS behavior - need I be worried?

[LittleClaire2]

I feel my 4yr old is a rounded little fellow, albeit a little serious at times, however he's showing some very weird behavioural signs at the moment, and I was wondering if I should be worried.
Let me give you a little background. His father and I split just before his 3rd birthday, and he will be 5 in the summer, and has no contact with his father at all. He rarely mentions him, just in passing. (I'm really unsure if this has anything at all to do with his behavior btw, and is actually irrelevant!) He started Preschool in September and appears to have lots of friends, will always tell me who he's spoken to/played with and if there were any issues etc, and his teacher said he's doing exactly as he should be and not to have any concerns what-so-ever.
Just recently, he's been turning all of his teddies away from looking at him, taken Toy Story stickers off his wall in his play room as he says they are looking at him, I have to turn around the matey bubble bath bottle in the bathroom as that is looking at him, and just this week, he has 1 large rubber duck and 5 baby rubber ducks on the side of the bath, and when I took him out of the bath I noticed that he had turned them all upside down.
Can anyone offer any advice, or maybe offer leading questions that I can ask to see if there is any underlying fundemental issues???
Thank you! LittClaire

Sometimes kids get little obsessions that take over for a while and then disappear. It might be nothing, or it might point to some underlying anxiety - you could just ask him something like "Why don't you like them looking at you?" and see what he says. If he's not sure then don't push it for the time being, and don't stop him from doing it or say it's silly - it could be the helping him to feel more secure. If it starts becoming a real obsession, as in, he won't leave the house till he's done it or it's keeping him awake at night, then it might be time to have a proper talk with him and perhaps look into something more.

Thank you, that's really helped put my mind at ease. I did ask him about the ducks and why they were all looking the other way, and he said that they were whispering about thier birthday. Sounded quite inoffensive, but our Mummy minds tend to work overtime, don't they!
Thank you again.

If it helps, when my nephew was 5 he had to have stickers put all over his bed head to cover up the knots in the wood - he said these looked like eyes and he didn't like them watching him. He's 10 now with no apparent lasting effects...

And what Cailin said

its the perfect age when they can develop their first proper fears. My DD has started to sleep with curtains open, door open, hallway light on etc. We've also got to take certain toys out of the room. To be honest, I wouldn't want a some of those toys staring at me in my sleep!
