Welcome back to dating jitters.
The only tips I have is to make sure you stay really in tune with your wife and her feelings. Even if she says she is fine, that can change on a dime, so keep asking. Better to annoy her with asking how she is too much than to find she has been hurting and you didn't know it. Otherwise, there's the fact that you need to make sure you balance your time and energy accordingly with your wife and daughter. Try to leave your excitment at the door about a particular person and use it to fuel a good home life.
