Decor for babies

Hi Folks

Need suggestion from creative ILites.

My 4 month old is focussing on objects and follows them through a distance. I dont have a crib!

I want to hang some soft toys,balls etc above my baby's bed. Since i dont have any hooks to do so, how can I go about doing this. I also have a false ceiling which doesnt hold anything even tried sticking a thread.. gravity problem..

... are welcome

Here are couple of things I can think about for now...

1. How about keep a rotating light (like the disco light, if you know what I mean) on the floor and it flashes color on the ceiling ....

4. I have actually hung small planes and things like that to the fan/light fixtures in my kid's room.

2. Get some animal/nature (whatever designs you want) stick on the ceiling

3. you can make bold design on paper and stick on walls around him

Let me think and see if I can come up with more. Are you not allowed to put nails in the ceiling - if yes, you get the hook type ones and it will make your job easy!
