Books about adding baby #2?

[MamaLump]

Hello all,
I am currently 10 weeks pregnant with baby #2. DS was/is a challenging baby, and I want to be as prepared as possible (I know it is impossible to be completely prepared) for adding another child. I'm worried about balancing routines, jealousies, and how clingy my DS already is (he is 18 months now, should be around 25 months when #2 arrives). Anyway, I'm headed to the library this afternoon or tomorrow, so I wondering if there were any books you could recommend.
Thanks!!
