Rails or No Rails

So I thought we picked out a crib this weekend:

but apparently we could be going down the wrong path of choosing a crib without rails - everyone we've discussed this crib with (who all have small children) and they have given us the same feedback - "you need rails".

So, I ask, "why the need for rails?"

We think the rails are for ease of use when a person of average or below average height may have challenges reaching over the rails to lay their baby down to sleep.

We are both very tall individuals so other than leverage to put our tax deduction in the crib, why else the need for rails?

I have received 4 phone calls from my mother since showing her the brochure for the crib about why it's the wrong crib (which in reality makes me think more of how right the crib could be).

We thought we were making progress by picking out baby furniture...
