Now if you don't know what giving birth is like, like me you might not want to experience it.  The best way that I could possibly describe it as female cramps times 100 (without any meds). The only way I could possibly come up with this is the fact that I have six sisters myself.  With all of that being said please keep in mind that Bulma is giving birth, and if you look at his first appearances that boy has a huge head.  So be warned Bulma's attitude will appear as weird but she is going through the most "beautiful" process in human existence.

"VEGGEEEETAAAA!!!!!!!!  Where is he?  Where's that no good, how dare he knock me up and leave me here with this baby!"

"Now did she decide to make this natural or does she want medication?" the nurse asked her mother.

"Well, I'm not sure I guess we could try the…"

"Are you both insane!?!  I want you to drug me until I see green men and little boys with tails fling on clouds."

"Oh, I guess that's a yes then."  Just then there was a nock at the door and another nurse popped her head through the door.  "There's a Vegeta out here to see you."

"Oh please, send him in."  For some reason everyone was looking towards the door save Bulma as she reached for the bedpan.  So you can guess what happened when he walked through the doorway to see the metal object inches away from his head. (It is too close to dodge.  She's a smart girl she can do the math besides it didn't hurt anyway.)

BBBBBOOOOOIIIINNNNGGGGGGG!!!!!!!!

"Son of a, what did you do that for woman?"

"What do you expect Vegeta, you impregnate me, go off somewhere for months where I can't find you.  You come back get in fights, and then when I need you the most on the day of our son's birth you're not here with me!"

"Woman are you drugged I am here now and unless you are fat my son hasn't come yet.  I did not come here to argue with you, I came here to be, to be…." He turned his head with a grunt hating to admit this "to be with you". 

Her eyes immediately lit up.  "Really Vegeta?"  Her mood changed like someone flicked a light switch.  (Honestly I figure the drugs kicked in.  I've been hospitalized it happens fast) "I was hoping that oh, OH, OOHHHHH!"

"What's wrong woman?"

"I think it's time, sir you'll have to step out now, most men don't want to see this."  A nurse answered him.  "Betty, could you page the doctor down here?"

"Sure"

Vegeta turned to walk away but was stopped by Bulma.  "Vegeta."

"Don't worry, I'll be outside."  She nodded her head in compliance as he stepped outside. 

When he closed the door the nurses looked at each other with a smirk and said just one word "Yummy".

The doctor was stopped by a spiked hair man standing in front of the door.  "Excuse me sir you're blocking the door."

"I assume that you're the physician looking after Bulma and our child."

"Oh, so you're the deadbeat who doesn't hold a job.  Well, I hope that if she has any sense Bulma will raise this child better than its father."

"Well then I guess I'll make this short." He raises his left hand into the air and creates a small ball of energy and makes it ripple out of con troll and the collapses it as he clenches his fist causing a loud thunderous noise in the process.  This is a little trick he learned many years ago that creates the desired affect that it has placed upon the doctor.  "If anything happens to my son, well, I don't want to have to finish my sentence."  He then stepped aside to allow her in the room.
