My kids are 6 and 4 months. Some days I feel like SuperMom, other days I want to pull my hair out. I've learned that its ok to drop the housework sometimes and order takeout. My kids aren't going to grow up and remember if I had mopped the floor enough, they'll remember if I took the time to play with them, read a book, take them swimming...being a parent is the hardest job in the world but it's also the most rewarding. My advice to anyone would be to take it one day at a time, don't sweat the small stuff and make time for you.
After all, we were women before we became Moms, it's ok to take care of ourselves too! And I remind myself that being a parent is a learning process. It doesn't matter if your kids are 5 or 25, we're all just learning as we go.
Oh well, that's my two cents anyway. Good luck!
