Child(ren) born in a Cusp?

I am a father of three beautiful children, they hold my heart and always will. However, I was pondering over some thoughts the other night and I realized that each of my children are born in cusps. At first thought, I was rather amazed. I mean, what are the odds of me having three different children, in three different years, and each be born in a cusp? Well, I'm not much of a mathematics person so I'll just go with "it's probably kind of low".

My eldest daughter was born on May 23rd (Taurus/Gemini). She is also blessed with a Leo Moon

My middle child, and second daughter, was born on January 21st (Capricorn/Aquarius). Also has a Leo Moon

Lastly, my youngest, and son, was born on November 25th (Scorpio/Sagittarius). I understand that he is close to the edge of the cusp, with his birthdate of the 25th. However, he definitely shows the signs of both zodiacs. Not to mention he has an Aries Moon.

Anyways, I am just curious to know if anyone might be familiar with these cusps and might know some information regarding them, knowledge that might be beneficial towards me understanding how they think or work, so to say.

My children have always been rambunctious and, how should I say, kind of off beat on how I remember myself being, or how I perceive a child should be. They are always deeply submerged into a lake of their own drama, in the aspect of them interacting together, and it drives me up the wall. Then, when I watch them, it looks like it's all absolutely natural to them.

Many Gray hairs have materialized on my head over they years, let me tell you.

Lol, well I am glad someone is finding delight in my gray coloring extravaganza. Here I always just thought my kids were just bad and then I find out, their built that way! Lmao

I'm a Cap/Aquarius cusper (Jan 19). I'm not exactly sure if I could give you any insight because your child's birth chart may be very different from mine. Anyway, I wouldn't say I'm off-beat. I'm odd, I guess- not around people I'm not familiar with though. My siblings think I'm "crazy". I do have outbursts of randomness but that's the only time I seem dramatic. I'm only trying to make people laugh. I don't have a lot of fights with siblings and usually never have drama... Ever. Your child's Leo moon may make them dramatic though. The way I "operate"... uhhh, I don't know. xD
