wow...you deserve a pat on the back. It sounds like you are a great guy and these kids
are very lucky to have someone like you to take care of them in this fragile time in their lives. I'll echo what others have said in that you kinda learn as you go. My son is 13 months and I'm still learning everyday. You have the want and the love to care for these kids and that is all you really need...the rest will fall in place as you go along. Your parents have been through this before...if I were you, i wouldn't hesitate to ask for help...I'm sure they'll understand
Good luck and I hope everything works out for you and the kids.
