Best wishes for your recovery.
I wouldn't worry so much about your children's moon houses in relation to your NN. Possibly you've got some ideas about karma in mind, but really, synastry goes by comparing two people's paired planets, notably the sun, moon, Venus, &c. Keep in mind that the moon does symbolize one's experiences of one's mother, but the moon also rules one's own emotional state and home, so you could have a great relationship with a child who had non-Mom emotional themes to work on in life.
Your little princess has her moon in Virgo sextiling your Cancer sun, and your suns are also trined. This should give you the ability to be friends as well as mother and daughter.
Your son has his sun in Leo conjunct you Venus, which suggests a lot of affection.
Emotionally both of your children seems to be extremely sensitive (moons in Virgo and Cancer) so I would suggest you find ways to discipline them or express your displeasure without trampling on their tender feelings. Your daughter also has a very sensitive sun-moon-Neptune in Pisces, trined by your son's moon; so if she has difficulty in expressing her feelings, your son can probably tune into them.
With your moon in the 5th house, you have a big commitment to both your children, so that's to their benefit. Your NN is at 27 degrees Aries, suggesting that your growth lies in pursuing your ability to be independent, but it's not forming a hard aspect to your children's planets.
Best wishes, Mama!
