Congrats!! Pictures pictures pictures =) lol.
My advice would be the same as Ashley, to read read read. You can never have too much knowledge. Find what methods work best for you such as diet there are soo many options I would suggest just reading them and finding which sounds the best for you and your family.
Also to go with your gut if you think something is wrong it probably is. Let your mommy instincts tell you.
They really are wonderful little creatures!
