The weird weights are a mistake on my part. Around the begining I was increasing Max's weight very quickly (to try and compensate for the square cube law) but when Jenna started growing I underestimated how much she ought to weigh. For story purposes, yes Max is hella thicc while Jenna is much leaner and is only just now starting to pack on some muscle mass. Once I have Jenna up to where she should be I'll be using the giantess converter (something I only recently discovered) on this site to make sure their weights remain appropriate. As for interactions with the parents, there will be more of that very soon, Jenna's been up to some shenangins so it should be interesting.
