K.A.
seperation anxiety begins about 18 months. That's really normal. My kids are always better behaved for others than they are for me....it's frustrating but better than the alternative. I would much rather people praise me for having such well behaved children eventhough they are difficult for me sometimes than they be terrors for others and I never can get a break because no one would want to babysit for me :) Good luck and hang in there, it will get better but they do tend to take Mom for granted don't they??
