Maybe it is a positive that he is vocalizing what he wants instead of just assuming it is something you would/would not agree to to. It could be an opportunity to open up communication in a more honest way. Is this something your H would normally do? Vocalize what he is thinking/wanting?
Also, maybe for him, he really is looking at it as an alternative to you being alone with the new baby. I am not saying its a great solution, but it shows he is thinking about it??
