Adam,

I asked my spouse what she thought some useful differences might be and she came up with two.

Be more agressive.

Do not admire, coo at, nor play with other people's children, especially babies. Her comment was that this was two-fold advice. First of all, it isn't something guys do, and second, you don't want to be thought to be a pedophile.

Hugs,
Persephone.
