I make 210k. ExH makes somewhere between 250-300k. We share custody and childcare expenses 50/50. We also each have a mortgage (and house maintenance, etc.) to pay.
Younger DC (2yo) is at a center that costs 2400/month (it's a sliding scale, so older kids are cheaper and younger kids are more expensive). Not cheap, but we really like the center and the fact that the teachers get paid better than the industry and therefore the turnover is low.
Older DC (who went to the same center from infant through pre-k) is now in a public school, so we only need to pay for after care and summer camps.
