Baskin-Robbins is offering all pregnant moms a free 3 oz. serving of its new “Soft Serve” ice cream on Wednesday, May 21st, between 11 am and 10 pm at participating stores.  They’re calling their promotion “Bump Day” to play off Wednesday’s nickname and all the pregnant tummies they’re hoping will come by their shops. It sounds like they’re not scrutinizing the size of the mommy bumps too closely (good thing for them!). Instead, they’re inviting all moms, whether newly pregnant or 9-months along, to drop by for the free ice cream.
