Hands down, I would have to say patience and guilt!!!  The two things I never really seemed to have a problem with before I had kids.  I mean I was such an amazing nanny…especially when I got to go home alone every night!!!  
But, now when I go to bed it’s usually with a heavy burden of wishing I had been more patient and guilt over the many ways I know I could have been a better mom to them.  It’s definitely the one area in my life that has humbled me and challenged me in learning how to let go of control…
