When I was a young man I believed a lot as your boyfriend does; children should be praised when they do something exceptional. As I grew older and raised more children, I saw this belief was a mistake. Children need praised a great deal, even for small things because it gives them confidence to do even greater things. It also shows them that you are genuinely interested in them.

As to nurturing behaviors. I was raised with very little contact at all. It made me feel unwanted, unloved and even a burden as I grew up. By all means, hug your kids, kiss them, pat them on the head as you walk by, anything that makes them feel wanted and loved.
