A wanted baby from a loving couple is always a joy. They will love being close in age when they get older. My 2, 21/2 years apart loved it when they were teens, they shared many friends and activities. It was also fun for them when they went places, as they could share rides etc. It will be very difficult at first, but figure that it will be for about 2 yrs, and that is not bad in the scheme of things.
There are many couples who would give their right arm to be so lucky to have 2 healthy children close together. So--- start enjoying, start making plans, find teens willing to come after school, to give you a break, stock up on diapers and anything to make your life easier.
You obviously were not concerned, because if you had been, you would have been protecting, so, enjoy what the 2 of you created.
