No, I don't feel nervous. He's a great father. Even if he doesn't do everything the right... er... my way.
I think the key here is that some things he will probably have to learn on his own. He will take the baby outside under-dressed. He will see the baby shiver or feel baby's hands when he gets back inside and realize it was too cold. He will remember next time.
For DH, it was taking DS out in the rain, at 4 mos old, without an umbrella, and seeing his big, wide eyes staring back at him, soaked to the bone, and with a little lip tremble.
That was a year ago and he still feels guilty! But he never takes him out when it could rain without an umbrella.
The best thing you can do, in most cases, is keep your mouth shut, and let him learn his own way.
And besides, you might just find your 16 month old
standing in the kitchen with matches and
a steak knife one day. When DH asked you
to keep an eye on him for a few minutes while he took a shower.
