With a 10 month old, you have no business keeping multiple firearms in rooms around the home.
Guess what the number one contributor to child mortality rates are in the USA? I can tell you right now it's not homicide or home invasion. Statistically, it is unintentional injury. Although most of us here on these forums own firearms and advocate for them, lets not be blind to the data. Unintentional injury is the number one killer of children in this country, and firearm related accidents are a part of that.
If you think your 10 month can't discharge a firearm, you are dangerously wrong. In some states, it is illegal to have a firearm within reach of minors. But illegal or not, it is generally a bad idea.
Find a firearm that is comfortable for you to carry. Alternately, invest in security measures that buy you a little time to get to your bedroom or wherever it is you keep your firearm when it is not on your person.
In my opinion, keeping firearms accessible around the house is not only ill-advised from a child management perspective, but also creates an indefensible tactical scenario. In suspected home invasions, a defensive strategy will almost always be the best option. This means finding a room where you and your family can lock the door, call the police, and - if necessary - defend yourselves using a firearm or other defensive weapon.
Going on the offense and clearing your house or running into a potential firefight with any number of assailants could quickly prove fatal to you. The offensive position requires movement, which gives away your position and by nature of movement puts you in non-optimal positions for surviving a gunfight. The defensive position which one may hunker down in and if necessary, strike out from, is the favored position.
If you do choose the defensive position, having firearms around the house can only work against you. You are now at risk of arming whomever is in your house against you - and risk turning what may have been a simple robbery into a two-sided gunfight. Alternately, you may fear arming your assailants and be tempted to leave your defensive position and compromise your strategy.
It is far better to keep your child out of harms way and prepare defensively by carrying around the home - which in some states, does not require a license - or by thinking ahead about potential defensive scenarios.
