Hi and congratulations!
Sun in Scorpio and Moon in Leo, both luminaries in fixed signs, means the child is going to be a very strong-willed and domineering person. Care needs to be taken that the Leo and Scorpio energy combination doesn't make the native arrogant and too opinionated. She will also be fiercely loyal. If she puts her mind to something, she will make sure she achieves it with, in addition to the aforementioned, Asc. ruler, Mercury, in conjunction with Saturn. Hence, all in all, the child needs to be shown early how to distinguish right from wrong, as she will develop her opinions/views quite early and hold on to them almost dogmatically.
Gemini Ascendant - she will be a friendly person, but also a little cautious, as Mercury (ruler of the Asc.) is conjunct Saturn.
Moon in Leo - she will be an outgoing and proud person, whose pride can be easily hurt. She will dislike being ignored and will love attention. Is she a thin child? Likely with a Gemini Asc., whose ruler is conjunct Saturn.
Sagittarian Merc. conjunct Saturn - she could develop her speech a little late and/or have an aptitude for numbers (maths/physics). Both Moon and Merc. in aspects to Saturn means that she will be sensible and cautious.
Both 9th house (higher studies) and 10th house (career and social status) rulers in Sagittarius - she could go overseas for higher studies, or could study law (could be international law, or something that involves foreign stay (like a foreign language, esp. with Merc. in Sag). She could also work abroad, or in a company/career that involves foreign travel/stay.
Gemini Asc. and Moon (3rd house ruler) in Leo, she will be good at school.
Jupiter in the 5th house, and 5th house ruler, Merc. in Sag. as well as a Leo Moon - the native could be active in sports/ recreational activities/ drama.
