With a small child do you really want all that glass within reach? I think they would look cool as a grouping on your buffet. I would do 5 (odd numbers more appealing). 1 or 2 could have a sprig of flowers in it. Group the 5 in the middle panel of the wainscoting, not spread out across the top.

love the light fixture above the table, may I ask where you purchased it?

I would display the three of them exactly as they appear in the World Market photo (depth of the buffet considered, of course). Or perhaps the center of the dining room table, if the space allows.
As far as the entry table, perhaps a few low succulents in small pots in different sizes and decor. Ditto on the small child consideration which is up to you. Mine (girls) did not, for the most part, break anything in the home. Everything expensive or breakable currently is up high or put away when the Twin Terrors (8-year-old boys) are here.

Very lovely room, btw.

I'm not too worried about the glass either on the dining table or buffet. The kiddos are getting to be pretty good about not breaking things (the high chair is on it's way out). I may just have to order the 3 and try them out.
