I didn't have a boat when mine were that young, but I'd give the following generic advice.
Know your sailing area, especially shoals, rocks, tidal/wind issues (winds out of the north-east make the mouth of the river here so bad small boaters are hanging on for dear life, or could even get swamped), local traffic (power boat wakes, jet-skis buzzing your boat), weather patterns (pop-up thunderstorms), things like that.
The

is probably one of the safest boats of its size out there, and far more stable than just about any power boat when the ballast is in, so I don't think there are any great risks here other than the usual, which you obviously planned for. Someone dedicated to the infant if things get hairy, proper infant PFD and other safety gear, fair weather sailing, and so on. Have a working radio or two, flares, sound device (Freon horn, in case you need to wake up a skipper who's sleeping behind the autohelm).
Again, having not actually done it myself, these are just personal musings, and they're worth what you paid for them.
