I really think that childcare should be the number one priority on your list.
Have you given it any thought at all? Not just the cost but what type? (home care, subsidized care, structured care, daycare institution?) Have you made yourself aware of the state of childcare in your community? Childcare generally involves lengthy waiting lists. Most of any reputable quality will have a requirement to interview the parents too. Most people get themselves on a list as soon as the child is born - or earlier.
You need to plan for childcare now - before you even get pregnant. Don't assume the right one will be available when you need it.
