No matter who you are or what you think about parenting, you will change when your little bundle arrives. You will change A LOT. Things will constantly surprise you. If you weren't flexible before becoming a parent well say goodbye to that. In my opinion parenting is all about going with the flow of things and giving your baby over to God. The two things you absolutely don't want to get caught up in are worrying and comparing. That can drown you.
Becoming a parent has changed me in so many ways. It has changed our marriage in so many ways.
When you are a parent a trip to the grocery store alone is like a vacation and a trip to a Target that has a Starbucks is like winning the lottery. When you do go grocery shopping as a family it becomes a team sport. 2 carts for the win.
When you are a parent your priorities shift. While your friends are still important to you, you don't care about missing out on things like you imagined you would. My happy place is at home with my baby in my arms and my husband sitting next to me (most likely with a cat on his lap.)
When you are a parent with a baby who doesn't nap often, but who decides to fall asleep on your 5 minute car rides, Drive-thrus become your best friend. Your poor oven will feel neglected unless you are heating up a freezer meal you made during your pregnancy.
You will miss sleep so much it hurts. When you do sleep you will dream of more sleep.
When you are a parent you will always be late and you will start to not care because taking care of your baby is more important and no matter what a poopy diaper just can't wait.
