How can we afford this?!

Why is baby furniture and necessities so darn expensive?! I don't know how we're ever going to afford all of this! We want to start our nursery ASAP but we were not prepared for so many obvious and hidden expenses. Is anyone else feeling completely overwhelmed by all of this? Our little nugget is only 15 weeks 4 days old, how in God's name can his things cost so much already?!
