You are not alone! I have tripped many a time over crawlers and walkers alike...they seem always to be right behind you and when you try to turn..whamo! However, I have been lucky that only once did I actually fall...well actually I tripped over something else and fell landing on a toddler He was not hurt, but was scared and I felt terrible telling his mom about it in case there were any bruises later I have learned to turn around slowly and carefully each time and not to make any quick dashes for any reason...always scouting what is around me (kids, toys, etc) and it has improved...but I can't tell you the number of times I have bumped a little one with my behind when I turn around
