Firstly- congrats! I am a new Dad to a 6 month old, and I can identify with the feelings you are having. Kind of the male equivelent to "nesting". I ran out and traded in my old car for a newer "safer" car within 2 months of finding out Lila was on her way, I upgraded our home as well to accomodate the need for more space.
After all is said and done though, I feel a bit silly. Here are the reasons why
Car- I traded in a car that was paid for and financed the replacement car- I feel a bit like a dummy, as I would really like to have that car payment cash in the bank every month now that my wife is no longer working.
House- When we found out Lila was on her way my wife and I were living in a 1 bedroom flat in Chicago. The price was reasonable, and the neighborhood was nice. In my zeal to get us more space I moved us into a much more nicely appointed, and larger 2 bedroom place at an additional cost. Funny thing about that- Lila sleeps in our room. We won't need a second bedroom for another year or so.
Of course, we then lucked out and I got transferred to Denver- so now we own a 4 bedroom house at a monthly cost that is less than that bigger apartment in Chicago, and we have 3 bedrooms we don't really need- YET
One day my wife and I were in the Lucky Brand store getting some Tshirts, and I came home with over $100 worth of baby stuff. Lila is already about to grow out of that stuff. we got about 2-3 months out of it. (dumb)
The reason I am posting this is because in my excitement about being a new Dad I probably spent a lot of money I didn't need to spend in the name of preparing for the baby. We could really use to have some of that money now.
My advisce regarding your cars is- take you time, make the right decision for you.
Some other advice...
I read several books, and that was a good thing. The best book I read was "Be Prepared"
http://www.beprepared.net/
After 6 months I can honestly say the book was the best $19.00 I spent.
I was also sure to attend all Dr. visits. This seems extrenuous sometimes- especially when there is more than one appt per week- but it is a good use of your time. Even though your significant other may
say it is no big deal if you aren't there- it actually can be- especially if unexpected bad news happens.
Not sure about other Dads on here, but I can verify that life changes a lot once the baby is born. The best thing about being an enthusiastic new Dad is that you won't realize how much everything has changed.
Example- I barely ever drink anymore. I used to go for beers at least once a week with coworkers and friends, but not anymore. I didn't even notice until a coworker mentioned it to me in passing. Do i miss it?
Well, I didn't even notice...
Your life adapts to the changes, and you go on.
I will also say that it isn't selfish to take a little time for yourself- I still went to Vegas with my buddies this year- but it IS selfish to not allow your significant other the same luxury. I try to make sure my wife gets to go out. She is hard pressed to travel like I did since she is breast feeding.
Most of all enjoy it- it's the best thing that ever happened to me i can tell you that much!
