You both spend 10 hours at work, per day. An 18 month old should be getting 11 hours of sleep at night. That would be 21 of 24 hours. So, you spend 3 hours per day and your DH spends, subtracting out the 2 hour nap, 7 hours per day. But you are the ones doing all the teaching and example setting? Equally naive.
Before everyone gets really excited, the following is an opinion---
And the people in the UK and US and wherever are equally wrong. It would be best if the actual parents stayed home with the child. Obviously not possible for both, so one of two.
Also, I think you can make an economic argument for two parents working and having to have some sort of childcare, be it DH, day care or grandparents. In which case, not ideal, but fine. However, the economic case has to be something more than affording the second BMW or 6,000th handbag or mommy or daddy feels that their career trumps having to care for a child. If they really feel that way, they should have just skipped the child.
