Congrats. Being a dad is one of the greatest things in the world. Nothing can rival the feeling! Be a responsible dad. Work twice as hard to provide and spend time with your kid(s). No matter how busy you are, create time.
And as @GG said, don't forget discipline. A majority of Kenyans are nowadays raising brats. Please don't be one of them.
Finally, you'll get all sort of advice from self styled experts - from relatives to friends. Do this, don't do this etc. Do your own research before you implement them. Read. Confirm with your doctor. Have a doctor or nurse on your phone book if possible. It comes in handy.
Again, congrats.
Never count on making a good sale. Have the purchase price be so attractive that even a mediocre sale gives good returns.
