Potential mother rant....
I think you did well and shouldn't kick yourself too much for forgetting your phone.
I don't have kids yet, but hopefully they will be coming along sooner rather than later. Still, the thought of someone hurting my child makes my shoulders tense and my teeth clench.
Not that even if it were a bad guy, they would be after your baby, but at times, when things go wrong, kids are a great negotiating tool to grab.
In your post you said that your child was asleep in the next room, but you didn't mention checking in on him, or pulling the door shut and locking it before your proceeded to get your gun. I'm not saying you didn't do it, you just didn't mention doing it. Because had it been a BG and you were upstairs while he broke in and was between you and your baby, I would hope your child would be secured at the very least but then again, I don't know the layout of your home. I'm just a potential mother throwing things out there.
My husband and I have considered this carefully in our preparation for parenthood. Our plan (to date) is for some kind of an intercom system from our room (or any room) to their room(s). When a code word or certain alarm is made over the intercom the kids will be trained to immediately close and lock their doors (deadbolts on the inside of their bedroom doors with the only keys in mine and my husband's possession). At which point they can return to the intercom and communicate with me or their father. Under absolutely NO circumstances are they to open the door themselves. Mommy and Daddy have a key. When all is clear we (my husband and I) will come and unlock the door. Even if the person at their door claims to be a police officer, or even claims to be us, they are not to open the door.
We are still working on the finer details, but that's the general plan at this moment.
I know that your child is too young to understand those kind of instructions, but having a plan for family should include their participation so that you don't have to put yourself through further worry and risk by trying to reach and protect them (which any concerned parent would try to do anyway).
I know it's just a fictional book, but in the book "Red Dragon" the BG comes into homes via their sliding doors, goes directly to the parents bedroom, kills the father, disables the mother and then goes to the rooms of the children and executing them. In the book, one of the children is dragged from hiding under his bed before he is killed.
I can only hope my children are trained enough to protect themselves at least to the point of immediately locking their door when feeling threatened, because Mommy and Daddy can't always come to the rescue. I learned that lesson the hard way over and over again when I was young and I won't let my children have to go through it as well, not if I can help it even in the slightest of ways.
I also want my children who are too young to understand getting up and locking their doors to be close enough to where I can go to them and protect them and if I'm alone, at least reach in the room, lock the door and proceed knowing at least that a BG is going to have to go through me (a mama bear) and a locked door before he gets to my child.
Like I said, I don't know your homes layout or your thoughts on this, but it's just a potential Mom putting out some feelers.
I still think you did well in your alertness and quick response and cool control. (where is that little thumbs up smiley?) :smile:
