A good gift for a father on father's day from a baby would be a mug or travel cup that has "world's best dad" on it. You could even go to the store "things remembered" and have something engraved on it such as his name and have it say "happy 1st father's day".
If they slept at all they would die

Because if they slept longer they would starve but they would rest in peace
You would be 273 years old.
8 hours is a third of a day, so you spend 1/3 of your time asleep. Therefore, in 75 years, you would spend 25 years sleeping.

it depends on the date of your last period day. This is because if you have sex with the boy you wont become pregnant that day. Doctors calculate from the last day of your last period. There are many due date calculators online. http://www.babycentre.co.uk/tools/duedate/
Ask with respect and treat the mother or father with it. Do what you say, and day what you will do...and mean it
