Great suggestions, thank you for taking the time to post them!
Given that I've created a player inventory & gifting system, it definitely makes sense to expand on this and add more options. Especially when it comes to clothes, so you can dress up both your character and the girls.
Feeder Feasts for the day trip locations make perfect sense. I'll add those in the next update.
I might allow the player to create new hose feeding variants via the cooking system I want to add, to bridge the gap.
I'd love to make the dates more varied and complex, so your ideas for 6 & 7 could help with this. Lactation isn't really my thing, but I may add it as an optional feature in a later update. :)
