WIP - Toddler food (Patreon)

Here's a preview of the September thema (toddler food).
There's a baby steamer that generates toddler meals (Sims don't really cook them, the tray appears just near the appliance).
I'd like to be able to make those trays eatable by toddlers in Sims 3 (they are in Sims 4, of course), but making custom food for Sims 3 is way more difficult than for Sims 4, plus I've never seen any toddler custom food for Sims 3, so it might be really challenging. Not sure I'll succeed!

The plan is also to make pouches, baby bottles (maybe generated from a bottle warmer?), plus another set of tiny chair & table.

I've tried very hard to make a chair booster for Sims 4, but it seems impossible. Sims 4 are way more pickier about their routing than Sims 3 and they simply don't want to use the booster if there's a chair under (it's much less interesting without! ;D).  :(

If there's any suggestion you'd like for this thema, I'm all ears! :)
