oh, i don't see why not! actually it could be pretty interesting to add another sibling into the mix to make the family even larger. their parents lived in poland until they got married and moved to the states to start a family and for their dad to go to medical school. they have 4 kids, and if we added the adopted sibling it would be 5 and i think i love that even more? they're just a big, loud family with huge hearts who like to eat food and mess with each other way too much.
