I can't cope with the high chair - the snacks given to the toddler in a high chair barely fill them up. A proper meal (I drag it to the floor in their room) will fill them up longer. I also have my toddler nap in the early afternoon, so they can get to bedtime without being in the red. They often stay asleep for 2-ish hours AFTER their sleep bar is fully green so IMO there's no reason for them to have the sleep need go into the red. Breakfast is waiting for them on the floor of their room when they wake up too.
And their potty is in the room too.
