Spawning In Plain Sight

I have to admit that we've been quite remiss as to the care of our one and only cactus plant, more or less leaving it to it's own devices .......

..... so imagine my surprise when I spotted that said succulent has been pretty much taking care of itself quite happily despite all this laxity .......

....... not only growing by at least a centimetre ...........

....... but also, in plain sight of all at The Towers, spawning tiny babies .......triplets in fact. This discovery was quite emotional, though tinged with an awful sense of regret that all it's stoic efforts have, until now, gone unnoticed.

I'm not sure how I/we can make it up, except for a little more water now and again to help to vitalise the mother, as well as keeping those little babies nice and plump ......... and then a lot of praise? Any other suggestions would be most welcome, especially from Mr D, who must find himself continually surrounded by cacti in the wild in hot and romantic Mexico and thus, no doubt, an expert!
