My sister's youngest 2 are 14 months apart. It was her 3rd child, and the OLDEST was only 3 1/2 when the last was born. All 3 were BC- OOPS I missed a dose- babies. She said "There isn't that much difference in the work of one child to two was very little." She said that when it was time for the older to do something then she'd do the baby too. (Diapers, eat, bath...) Although... this is when she left the work force. She said that 3 kids in child-care was more than she got paid.
If this too will be your situation, then now may be the time to look into a home business. I've heard Aurbon and Pampered Chef both pay very well. If you can afford it and are intrested, AND have the time, I've also heard that At home Medical Billing pays pretty well. I wish I had done the training while we were still dual income. Now we just can't afford to get started.
Most of all (if you believe in God) know that God is bigger than all of this. This child is intended as part of HIS greater plan. You are VERY blessed and fortunate. You will figure it out, you just might have to give up a luxury or two. You will be fine~ J.
