If you put minimal effort into controlling costs this actually makes sense. But for a real-life example, my family of 3 (one kid) has expenses of about <1/3rd of that, childcare included.
That's a pretty real-life example. Are you an owner in that area that bought in the last three years? How long were you wait-listed on daycare? How close to fidi are you? If you're willing to cart your kid all the way to the sunset every day you can find cheaper daycare, or if you're renting your costs are going to be way lower.
