Lala, unfortunately there are bad and really unscrupulous astrologers out there, who will give a really crummy reading for a tiny child. Sometimes they will offer to help you mitigate his challenges-- for an additional fee. I don't know who gave you that horrible reading, but s/he was highly unethical.
I don't view natal chart readings as a kind of fatalistic fortune telling. I don't think our futures are so pre-determined. Each planet, sign, and house has multiple interpretations that are consistent with their core meanings. The key in raising a child is to focus on the empowering meanings, not the disempowering ones. (This is called choice-centered astrology.)
With CJ's sun in his 7th house, some kind of partnership will probably be very important to him. As a child, a partner might be a best friend. When he's an adult, he will want to be part of a couple, whether he is in a relationship or not. The 7th house can also relate to "open enemies", meaning the ones we know about, not the secret back-stabbers. If you find that your little guy has a tendency to think of someone as his enemy, see what you can do to help him resolve the situation.
My sun is in Aquarius, too, and I think it's a great sign. Aquarians need our space, however, so don't be surprised if CJ isn't always as demonstrably affectionate as you think he should be. He is, in his own way. If he shows any interest in science, please encourage him.
With his moon in Sagittarius in the 5th house, your son may well become interested in travel and outdoor recreation. The moon shows one's emotional nature. The moon also represents his experience of his mother. I don't know why the chart doesn't show a sextile (favourable aspect) between the sun and moon, because it's there, and it shows a nice flow between his sense of identity (sun) and you (moon.) In the 5th house, CJ's moon also suggests that he will want his own children when he is older, or perhaps become a teacher.
In terms of stuff to watch out for, your little guy has a formation called a grand trine, which looks like a blue triangle linking his moon, Uranus, and Jupiter. While this suggests an easy flow of energy, sometimes life goes well enough for such people that they don't have a strong sense of motivation. Motivation to get up off the couch and do something tends to come from the red lines, like the squares.
This is where maybe the other astrologer related your son's 8th house Venus-Mars-Chiron to becoming a pimp. (Yikes) Periodically there are generations of kids with a stellium (collection) of planets in a given sign or house. It's as though their generation will have a particular set of issues to address. Among other things, the 8th house rules the sexual organs, and Venus and Mars are the sexy planets. But obviously, there is such a thing as a healthy sexuality. I think it would be a good idea to ensure that your son gets a healthy, positive sex education when he is old enough to make sense of it, together with the cautions that caring parents need to give their children these days. (Vs. learning about sex "on the street" via equally uninformed peers.)
The 8th also rules investments and money that is shared in some way with other people, and the death-rebirth cycle. Children can always learn about sharing with others. When your son is an adolescent or young teenager, he might enjoy putting some money into a safe stock and following it in the stock market.
If your home is set up for this or you can join a community garden, your son might enjoy digging in the dirt (and what child doesn't?) and planting a little garden where he learns about nature's cycle of birth, life, death, and rebirth of new growth in the spring. If he knows someone who died (like an older relative,) speak frankly with him about death. He may be curious and won't need any sugar-coating (like "grandma went to sleep") to make sense of physical death.
Both of you should enjoy Halloween-- making "scary" costumes and perhaps making or visiting a "haunted house." (As a kid, my friends and I sometimes made a make-believe haunted house in the basement. Very Plutonian.)
Similarly, thinking of that previous chart reading you got, gambling is a 5th house matter-- because the 5th house rules both children and pleasurable leisure activities of various sorts. (It also includes going to the theater.) I don't gamble, but I also have a 5th house emphasis. "My" 5th house relates to my children and to outdoor recreation.
Speaking of the theater, another good 5th house activity would be to put on impromptu puppet shows at home, or take him to see a children's theater or street fair if there is one in your area.
Children are so special, Mama-- as you know. Your little son is lucky to have a mother who wants the best upbringing for him.
