In my experience this leads to drastically less sleep. You disturb your baby and your baby disturbs you. We put the baby in another room and invested in a baby alarm.
* Seriously consider breastfeeding.
Yes, but don't pressure yourself too much...the most important thing is that the baby eats properly. Bottle feeding gives you the critical advantage of being able to measure how much the baby eats.
* Don't waste your money on a change table.
I would say invest! After a week or so of leaning over to change our baby it really affected me sitting at the computer to code. Bad back means bad news for your startup.
