Haha, well I used to say to dd, 'if you're rough with ds you just show him how to be rough to you' and little did she know how true that was. It's such a balancing act. You're doing a great job. I know where you're at and it does get easier, but like all parts of parenting change brings good and bad. Hang in there. Trust yourself and remember you're working on a big picture so don't sweat the small set backs or off day.
