My wife is a mannequin and just gave birth to a baby. Is it appropriate to invite photographers to shoot at home during lactation?

If it's normal work, why not? It means that your wife really cares about her family. Just after giving birth, you should continue to think about making money. You should work harder. Don't let your wife hit you so hard. At least you have to play better than her, or you won't be in the same class. Treat your wife well. Taking care of the baby every day is actually very tiring.
