i am installing a safety gate and since he was just next to me i let baby play with the box and stuff around.. i noticed he is chewin on a plastic thing.. thats no biggies and i would normally have let him play with it as it is pretty and wont choke on but this time i had to check and make sure.. when i look at the plastic thing i noticed he was chewing on something so i put my finger in his mouth and i removed a screw.. a freakin screw!! the little bag with the screws was not close by, i dont know how he got his hand on it.. he was sotting right next to me. like so close we were touching each other... i was seeing him in the corner of my eye, talking to him and looking at him in between each step of building the gate (wich took me around 5min) and i tought he would be safe next to me.

boy is okay tho.. he got scared of my reaction but he didnt get hurt... but i cant put words on how i feel
