If your wife is breastfeeding, are you planning to get a breastpump? If yes, you might want to consider bottles that are compatible with the breastpump.
Another suggestion is not to get too many or ANY of the small capacity bottles (4 oz), they dont't last you for very long
To avoid issues with nipple confusion, try to avoid introducing the bottle in the first few weeks, let your wife establish her milk supply first via direct latch.
Congrats on the baby, btw!
