Congrats!!! If you are ready it may prove to be the best thing you have done. Here is a bit of advice, hope it helps your young one develop into a splended person.
1) Go to birthing classes, and if you and your wife can, deliver vaginally (helps baby immensely)
2) You and your wife get parenting classes: learn about lifespan development, authoritative parenting practices, discipline techniques
3) Research milestones,know what the doctors will be looking for from your child and why they are important and prepare them for it, e.g tummy time to strengthen lifting their head
4) Learn about sleep schedules and feeding schedules. How much sleep they need at each developmental stage, and how much food. Get them on a sleep schedule so you can predict when they will be awake, and train them to sleep through the night.
5) Change your diets, remember from prenatal to 2, your child is being hardwired to live in a specific environment so be wary of what you put in your bodies and your child's. Additionally, try to avoid any screen time, tv, phone, laptop, for the first 2 years of your child's life. You want them to develop in a world devoid of super stimulating, loud, and unrealistically fast and bright stimuli.
6) remember you are creating the environment that will lay the foundation for how your daughter will expect to be treated, and in turn, treat others.
