I was on this thread yesterday and have followed the OP's posts.... I find it very telling that at no point in any of the discussion has he or, according to him, his wife, considered or made their choice based on what they feel is best for their DD. Its all about their lifestyles etc.
Surely surely we make decisions as parents by first thinking about what is best for our DC and what our priorities are in terms of child rearing, then together, we think through the practicalities of how the "parenting team", between them, can make that work....
So, if you decide that a SAHP is important and what you think is best for your DC, you decide between you how that could work and, if it can't financially, you work out how to get as close to what you think is best for your children as possible?! (e.g. one of you working p/t etc) No?
I don't get the OP's attitude frankly. He cares about whether his wife is expecting to be supported and getting an easy ride (which incidentally is an understandable annoyance)... but is that really the point? I also don't understand his wife needing a to send a 16 month old to nursery when she is at home f/t, but perhaps my DH (a SAHD) would!
OP - what do you think is best for your DD and, given the realities of life, finances etc, how can you, between you, get close to that?
Seriously - isn't this what everyone does?
