My best advice for first time parents,
SLEEP WHEN THE BABY SLEEPS.
I know this probably has already been heard billions of times, but it really does help. Having a baby is absolutely exhausting work, so take advantage of nap time, dishes and chores can wait. Napping will help when the baby wakes up at all hours, you wont be so sleepy or cranky. It also can help lesson the chance of postpartum depression, because it will ease the stress a little bit, and take it from me, postpartum depression is not fun.
Keep baby oragel handy, they will be teething before you know it. Also, gas drops are a must have. Some baby's (like my son) have an extremely hard time burping, and this can lead to hours of the baby, and you, crying out in frustration.
Always remember: It's just a baby. They can't tell you how they feel or what they want, and yes, sometimes babies just need to cry.
If you feel too overwhelmed with everything, put the baby in a safe place, like it's crib, and call a friend or family member to help out.
