I will only use two words to offer "help"...Bag Balm (human version, of course)...

My poor DW took a beating with one child; can't imagine two. It really helped a bunch. So much for two words.

The fun starts at the delivery. What an awesome experience. Watching new life begin will change yours forever.

Have fun and welcome to the parenting fray.

Congratulations my friend.
