Now that I've, ahem, graduated from the status of new mother to the glamourous (not :) position of a toddler's mom, I've got a few pointers for you, oh inexperienced fresh-out-of-the-hospital mommies. Preggos can benefit from these too, though you might want to enjoy blissful ignorance while you can.
So, a few things I'd avoid if I were you...
These are people that will tell you the baby will die if he/she eats something non-organic, become autistic if you turn on the tv, and have psychological issues if you go out on a date. Now, of course I'm exagerating here, so I'm not saying don't be careful, but I'm just saying, don't be scared all the time. Then you won't have time to enjoy the baby.
Super Mom Syndrome
You cannot, physically, be with your baby at all times while keeping a spotless house and looking like the cover of Parents magazine. I'm sorry. Please lower your expectations of yourself and what you think you're supposed to look like or achieve in a 24-hour period. This does not make you a failure; it makes you a more mature person who'd just discovered the value of rest. You will find your new, baby-friendly process of doing things, I promise.
I know, you love your baby; he/she's the best friend you ever had. Totally accepting when you emerge in the morning with your hair up and 2 days ago's makeup, dependent on you like no one else. It's good to feel needed, and heck, it's just addicting to hug our babies. But please remember, there are other people who love you. People who would love to get a call or email from you, just to remind them that you still care, and don't just have space for your baby in your heart. Which brings us to...
Remember, your husband? True, he looks even better as the father of your child, but he is, still, your husband. You're still supposed to go on dates with him, and enjoy his existence. I know, the baby takes out your heart, your soul and your body, but you'll just have to discover a way to love your husband in your new role. You're both different now; it doesn't have to be the same as pre-baby days. But he can be your shoulder to lean on, and someone to remind you that you're still pretty awesome by yourself, without a baby attached.
