As a father and a new carrier, I bring this question up because its one that's bothered me. I began to think of all the different methods possible to defend myself, the outcomes of giving all my possessions, and nothing honestly was a good idea. The best cased scenario is you have enough items of value and a nice enough attacker to let you and the baby walk away, worst case is you become another Brunswick murder. As recent events have proved, the world has become a sick place. As a father, I know how distracting a young child can be, and a distracted father is a prime target. The problem with fighting back is there's already a gun in your face. Can you draw and shoot fast enough before an attacker armed even with a knife can get you? Who is to say as soon as your gun is exposed while reaching for a wallet you're not shot? Its really a trick question because regardless of whether or not you have a child, you should always be aware of your surroundings enough to notice and address a potential threat before you get caught in the reaction curve, it means scanning your surroundings, knowing what's in front, behind, and beside you at all times. Scan your surroundings as you're putting your child in their car seat. Carrying a gun is no good if you can't use it, you have to give yourself time to draw and shoot. You may still have to put your body between an attacker and the baby, but the difference is there isn't already a gun to your head or a knife to your throat. We've all heard of baby brain, but many think it only happens to pregnant women. Try to order a meal with a screaming baby and a daughter that suddenly has to use the bathroom, which is why mothers are prime targets, they're distracted. Always be aware of your surroundings.
