If you both work full time and your parents or ILs watch your LO during the day, how do you coordinate with them? What do you do if they go on vacation or are sick? Do they watch LO at your house or theirs?

My ILs have offered to watch our LO (due in November), at least for the first year or so. I'm tempted to take them up on this offer since I know day care is expensive, but I'm wondering about the logistics and about what sort of contingency plan we might need to have in place if they're not available. Any insight from your own experience is appreciated!
