Hold onto everything, and figure out a way to pay for the baby.
I won't sell anything outright without a replacement until after the coming Pres. election, and perhaps a bit beyond. I've sold many, many firearms over the years with the explanation to myself that I can replace them later. To date, I've yet to replace a single one of them. Most missed were some beautiful S&W and Colt revolvers and semi-autos, old Winchester bolt and lever guns, AR's, and, well, you get the idea.
Remember how tough it was to find ANYTHING chambered to .223/5.56, .308, 9mm, .380, .357, .44 and .45, much less the ammunition to push through them after O'Bummer was elected? Couldn't even get .22 LR in ANY configuration for several months, and primers were absolutely impossible. I also remember seeing powder go for outrageous prices, including several internet auctions for Varget, that went $600+ for an 8 pound keg.
Beyond all of that, there are days when the family shows up, and a trip to the sandhill happens, and almost one of everything goes out, and gets used. You might also want to consider way down the road, when one of them young'uns wants or needs, or just becomes interested in shooting, and asks to borrow something. There's a name, other than mine, attached to everything in the safe for "just in case" something were to happen to me.
Do what you want, and please understand, I'm not claiming that the sky is going to fall,...yet. Just, well, a fella might want to CYA for awhile, you know?
