Easy if you have one child. Not too hard to move. But the child has siblings. Not so easy to move the whole family back to the room each time the little tyke wants to nurse. And I'm sure the child is wanting to breastfeed a lot.
I think all places should allow babies and toddlers to eat....whether that be breastmilk, formula, or some kind of crumb-free snack. Older kids (depending on health and family situation) could probably wait.
The only exception I would see is places that are adult-only.
But if you're going to allow toddlers and babies, they should be able to eat.
If you have a fancy store and don't want milk dripping on the expensive furniture...provide a lot of benches.
Very sad that this is a Ronald McDonald House.
