That is the “lenited” form of baclainn. It’s sort of the same word but pronounced differently. You wouldn’t use it that way by itself ever. The “b” becomes “bh” when following certain other words or sounds and to signify certain other meanings grammatically. For instance, “ina baclainn” means “in her arms”, “ina bhaclainn” means “in his arms”.
