Hi One Trick Pony, my boys are spaced about the same as your children will be. Let's see:
-First off, don't forget, you have 10 full moons before your next babe arrives. Your first will be much "older" by then.
-Involve dp as much as possible with dc#1. So when dc#2 comes along, dc#1 will feel that much closer to your dp.
-My dh handled bed time (we all co-sleep) with ds#1 when ds#2 was a colicky infant.
-Take dc#1 to mid wife/doctor appointments
-Don't worry about what the house looks like, just play, nurse, and hold your children.
-The sling is essential to my daily life. How else could I nurse my ds#2 down for a nap while kicking a soccer ball around the yard with ds#1?
-Take any help that is offered to you.
To be honest, it was hard for me at first and I felt a bit overwhelmed. When ds#2 hit the 6 month mark, things just kept getting better and better. The first thing they do when they open their eyes in the morning is seek the other one out, wake each other up, and roll around in the family bed hugging and laughing.
Feel free to PM me any time.
