I havent dropped Dominic either,but he did roll off the bed a couple of times about a month ago,when we were cosleeping and feeding in bed of a morning!!! Poor little man,lucky the pile of clothes was there for him to fall on!!!
Debbie,i have done the car door thing too,but i really hate it when they throw themselves back as you are walking through a doorframe or something,and they clip themselves on it....
