We'll certainly teach our kids Tagalog also and some Surigaonon in time. It will be useful for them as we hope to go and live in da Phils at some point, even for just a couple of yeas.
I'll teach them a few basic words in Yoruba, but as I don't much like Nigeria and have no intention of ever going there again, there is little point in teaching them more than that (a little will keep my mum happy, ;-) )
