Size of an average rutabaga

Dad called his good old friend 'Guru' when he found out that i am on my way to join their life. He gave a good idea of what to expect during the coming months, things that got to be done during the early/later days, how to take care of me when i am inside mommy's tummy and many other important related stuff about me in general terms.  I think mostly if i meant 'me' you guys would have guessed  that includes mommy also! One of the main thing dad found out that day was there isn't a 'Undo option' for whatever thats going to roll over them in the future :)

Anyway, Guru asked dad to subscribe and to be active  in two/three websites that majorly revolves around guys like me before he hung up. Babycenter.com, babyzone.com were on the top of his list and dad subscribed to baby center and mommy to the later. later they found out that babyzone was very average or at least not on par with baby center in many of the cases. Meanwhile, baby center has lot of cool features and it also sends an email every week that discusses about my developments, what changes to expect during that week and top questions etc...

One things both the parents look forward in that email is my growth. The email will contain a picture of a vegetable that is comparable in size/weight to me that week. Hence, every week i will be one kind of vegetable in their mind :) I think they started looking the weekly email when they said i will be like a "lentil bean". Till this week, they know almost all of the vegetables that is used as an metaphor for my growth. Right now i am like an average rutabaga but what is this vegetable is the first thought that came to their mind after seeing the email today...
