Awe, try not to feel bad. We as moms are not perfect. We have a three year old, and while she is mostly well behaved, she has her toddler moments of course. What I do when I'm frustrated with her is go into our bedroom and slam the door behind me and give myself a little time out so I don't destroy something in front of her (like put a hole in the wall or something). I feel like a monster when I need to give myself these times out because she bangs on the door and tries to get in and screams mommy mommy! But it's better than having a temper tantrum in front of her I guess. (I admittedly have some anger issues once in awhile obviously!)

Maybe try giving yourself a time out like that if you start feeling frustrated with your son again.

It usually only takes me about five minutes to cool off.

Anyway, just an idea.

Good luck at your interview!
