do you keep spare batteries around the house?
what size?

This is an odd topic, lol. But yes, we buy them in bulk at Sam's in all sizes (AA, AAA, C, D)

We also keep spare batteries, usually AA or AAA.

Are you warming up for March Madness? lol AA, AAA, C, and D. You never know what toy will run out next.

I don't think we have any C's because nothing in the house takes them. We have D's (only Sophia's bouncer takes those though) and AA and AAA for remotes and my camera.

we usually have a stock of AA and AAA around
