First of all - Congratulations.
I have 3 daughters, so I have been through this a few times. You have received great advice from the members on the forum and have little to add. Like many, I subscribed to the idea that your mind is the best survival tool you have. That all of the kits, supplies and hardware you have are nothing more then the icing on the cake if you have prepared yourself mentally and spiritually through training and thought. Likewise, the best advise I can offer you is not what is; the best crib, book to read, class to take or car seat, but rather suggest you approach this most important stage in your life with love and awe.
Be happy-
Love your wife, and make sure she is the best friend you have in the whole world. Make your family a haven where your children can turn to in times of trouble. No matter how well or poorly they meet your expectations, make sure they know you love them and can always rely upon you. Whatever your religious beliefs might encompass, rely upon what strength you derive from that belief and know you are not alone in the world.
Be happy-
Every child is different, some will challenge your every moment of existence, and some will just fall naturally into the dynamics of your family. Some may be just like you, others as different as day and night, but all will change you forever.
Most of all – Be happy
Pete
