In no particular order:

• 2.5 hours of sleep is starting to feel like it’s enough
• I now know exactly how far to put the bottle’s nipple into Will’s mouth to facilitate optimum feeding
• The terror of picking him up has subsided
• My hands constantly smell like wet wipes
• I know the difference between “something’s wrong and I’m uncomfortable” crying and “come here and pick me up you heartless bastard” crying

This being a dad thing is going to work out just fine.
