LOL I know, sorry ;-)
The best advice I can give you is to make sure you love your baby's mother.
Mothering is exhausting.... you need to see your wife as having a cup of love that she constantly pours out to the baby. Your job is to refill that cup with more love, so she will be refilled. This is particularly true in the first three months.
The more you can do for her, to make her feel loved, the more love she will have for your child. This investment will pay dividends to the end.
Just joking.... Kids will make you young again and old at the same time.
